In modern immunology and cellular research, isolating dendritic cells accurately is essential for studying immune response mechanisms, developing vaccines, and even working on personalized therapies. One of the key steps in the isolation process is sample preparation—especially when it comes to separating cellular components without contamination or damage. That’s where Lab Cell Strainers play a crucial role.
Researchers rely on tools that are simple, efficient, and minimize sample loss or contamination. The SnapCap Lab Cell Strainers from PluriSelect-USA answer this call by offering an integrated straining solution that streamlines workflows and ensures consistent results. Built to handle the nuances of cell isolation, particularly for delicate cells like dendritic cells, SnapCap Lab Cell Strainers bring together functionality, hygiene, and ease-of-use in a compact format.
Understanding Dendritic Cells and Their Isolation Needs
Dendritic cells are essential sentinels of the immune system, acting as messengers between the innate and adaptive immune systems. They detect pathogens and present antigens to T-cells, triggering targeted immune responses. Given their pivotal role, dendritic cells are central to immunotherapy research, cancer vaccines, and infectious disease modeling.
However, isolating dendritic cells can be technically demanding due to their rarity in peripheral blood or tissue samples. These cells are sensitive to physical disruption, so the sample preparation process must be both gentle and precise. If not handled correctly, the process can lead to loss or damage of cells, compromising downstream applications such as flow cytometry, cell culture, or cytokine analysis.
Why the Right Straining Solution Matters
Before dendritic cells can be sorted or enriched using antibodies or density gradient methods, the starting sample—be it from blood, bone marrow, or tissues—must be free of debris, clumps, and unwanted particles. This is where Cell Strainers come into play.
A Cell Strainer is designed to filter out detritus and aggregates while preserving viable, single-cell suspensions. For delicate cells like dendritic cells, an ideal strainer must:
– Avoid applying excessive shear stress.
– Be sterile and contamination-free.
– Fit seamlessly into standard laboratory workflows.
– Offer a range of mesh sizes for different cell types and tissues.
This is exactly where SnapCap Lab Cell Strainers stand out.
SnapCap Lab Cell Strainers: Built for Efficiency
SnapCap Lab Cell Strainers are specifically engineered to optimize sample preparation by combining a test tube and strainer into one single, sterile unit. Unlike conventional setups where researchers place a separate mesh insert into a tube, SnapCap streamlines the process through innovation.
Key Features and Design Innovations:
1. Integrated Test Tube and Strainer:
The SnapCap Strainer uses the screw cap of standard test tubes as housing for the nylon mesh. This design reduces the handling time and eliminates alignment issues common with separate strainers and tubes.
2. Snap-Lid Mechanism:
The cap is easy to open with a single hand using your thumb, allowing for quick processing without disrupting the sample integrity. This feature enhances user convenience, especially during repetitive tasks or high-throughput sample preparation.
3. Sterile and Safe:
Each SnapCap Lab Cell Strainer is pre-sterilized, ensuring that there is no microbial contamination—a vital requirement when working with sensitive immune cells.

The improved version of SnapCap is equipped with an elastic sealing ring, making it both airtight and leakproof. This becomes especially important when working with biological fluids, maintaining sample integrity and preventing leaks during centrifugation or transport.
5. Variety of Mesh Sizes:
Available in 40 μm, 70 μm, and 100 μm mesh sizes, researchers can choose based on the type of tissue and size of the target cells. For dendritic cells, a 70 μm mesh is often ideal as it efficiently removes debris while preserving viable cells.
Streamlining Dendritic Cell Isolation: Step-by-Step with SnapCap
Here’s how SnapCap Lab Cell Strainers can be seamlessly integrated into the dendritic cell isolation protocol:
Step 1: Tissue or Blood Processing
Whether you’re working with peripheral blood mononuclear cells (PBMCs), spleen tissue, or bone marrow, the first step involves mechanical or enzymatic dissociation of the sample. This step often produces a mix of single cells and clumped tissue debris.
Step 2: Straining the Sample
Immediately following dissociation, the sample is passed through the SnapCap Lab Cell Strainer. The integrated design allows the researcher to pour or pipette the sample directly into the tube. No need to hold the mesh or align it manually.
The nylon mesh gently removes aggregates without applying stress on the viable cells, maintaining the health of fragile dendritic cells. Unlike some traditional strainers that may clog or collapse, the mesh in SnapCap remains stable and taut, ensuring uninterrupted flow.
Step 3: Downstream Cell Separation
Post-straining, the clean, single-cell suspension is ready for downstream processing. This can include:
– Antibody-based Cell Separation using magnetic beads.
– Density gradient centrifugation for enrichment.
– Flow cytometry for sorting and analysis.
By starting with a well-strained sample, researchers reduce the risk of clogging in FACS machines and improve the accuracy of sorting, which is especially important when isolating rare cell types like dendritic cells.
How SnapCap Supports Particle Separation Techniques
Beyond dendritic cells, SnapCap Lab Cell Strainers serve a broader function in many particle separation techniques used across cell biology. In addition to removing tissue clumps, they help in separating microbeads, cellular debris, and even large apoptotic bodies from viable cell suspensions.
SnapCap’s design ensures:
– Consistent pore size distribution in the nylon mesh.

Choosing the Right Mesh Size for Dendritic Cell Isolation
Picking the correct mesh size isn’t just a technical detail—it can directly impact your isolation results. Here’s how you can make the right choice when using SnapCap Lab Cell Strainers:
– Use 70 μm mesh for most dendritic cell workflows:
This size offers the best balance between removing clumps and preserving dendritic cells, which typically range from 10–20 μm.
– Choose 40 μm for smaller cell types or debris-heavy samples:
Ideal when working with lymphocytes or very fine tissue homogenates, where smaller debris needs to be removed effectively.
– Opt for 100 μm mesh for initial rough filtration:
Perfect for fibrous or complex tissues (e.g., spleen or tumors). Start with this size to prevent clogging finer meshes during subsequent filtration steps.
– Consider a two-step filtration process:
Begin with 100 μm to remove large debris, then re-filter through 70 μm for optimal purity without sacrificing yield.
– Match mesh size to tissue type and preparation method:
Soft tissues like lymph nodes may only need 70 μm, while tougher tissues like tumors benefit from starting with 100 μm.
– Don’t ignore flow rate and pressure:
Smaller meshes slow the flow and can clog more easily, so balance is key for maintaining viability and speed.
– SnapCap gives you flexibility:
With all three mesh sizes available in the same easy-to-use format, researchers can tailor their workflows without switching devices or brands.
Integrating SnapCap Strainers into Automated Workflows
As laboratories increasingly turn to automation to improve consistency and throughput, it’s essential that lab tools are compatible with high-throughput systems. SnapCap Lab Cell Strainers are not only suitable for manual workflows but are also ideal for integration into semi- or fully automated lab systems.
The uniform design of SnapCap tubes and their compatibility with standard 50 mL conical tube holders make them ideal for robotic handling and automated pipetting platforms. Since the strainer is already fixed within the screw cap, there’s no need for alignment or manual setup, reducing preparation time and increasing process reliability.
This plug-and-play functionality is particularly beneficial in biopharmaceutical and contract research organizations (CROs) that process hundreds of samples in a day. Automation-friendly design minimizes human error, improves repeatability, and keeps the filtration process contamination-free.
Another key benefit in automated environments is the snap-lid mechanism, which allows one-handed operation without risking spillage—something that can easily disrupt automated stations if standard strainers are used. SnapCap’s leakproof seal ensures that samples stay contained during transport between instruments or centrifugation steps, helping maintain the workflow’s integrity.
Moreover, SnapCap Lab Cell Strainers reduce cleaning and maintenance efforts. Being sterile and single-use, they eliminate the need for cleaning validation—one less bottleneck in regulated or GMP-compliant labs.
For labs looking to scale up while maintaining quality, SnapCap Lab Cell Strainers offer a forward-compatible solution. Whether it’s for small-scale research or high-throughput sample preparation, these strainers help bridge the gap between manual and automated lab environments.
Optimizing Viability and Yield in Cell Separation Workflows
In cell separation, especially when isolating rare or fragile cells like dendritic cells, the balance between cell viability and cell yield is a constant challenge. The goal is to maximize the number of viable target cells while minimizing stress or damage during preparation. SnapCap Lab Cell Strainers contribute significantly to achieving this balance.
One key factor in maintaining cell viability is minimizing mechanical stress during filtration. Traditional mesh strainers can collapse, causing backpressure or inconsistent flow rates. SnapCap’s rigid nylon mesh provides stable filtration, allowing for smooth, low-pressure flow and preserving cell integrity.
Researchers can also improve viability by ensuring the buffer solution is kept cold (typically 4°C) during sample processing. SnapCap’s sealed design helps maintain consistent conditions and reduces evaporation, which is especially useful during longer prep times or when working on ice.
To optimize yield, it’s crucial to avoid unnecessary cell adhesion to plasticware. The SnapCap’s smooth internal surfaces reduce cell adherence, ensuring that more of your precious dendritic cells remain in suspension and make it through to downstream applications.
Additionally, using pre-wetted strainers and gentle pipetting techniques can further increase recovery rates. SnapCap’s ergonomic design—particularly the thumb-friendly snap lid—encourages gentle handling, reducing turbulence that can lead to cell death or loss.
Combining SnapCap with other good lab practices—like avoiding over-digestion during tissue dissociation and using DNase to reduce clumping—ensures a cleaner, more viable single-cell suspension.
In high-stakes experiments where every cell counts, SnapCap Lab Cell Strainers help researchers strike the right balance between yield, viability, and workflow efficiency.
