The Mouse Naïve CD4+ T Cell Isolation Kit was developed with BACS™ Microbubbles for the enrichment of untouched Naïve CD4+ T cells. Unwanted cells are depleted through negative selection.
This kit can process up to 1 billion cells
Fast & easy workflow enriches splenocytes for Naïve CD4+ T cells in 30 minutes
No magnet, no column, no harsh chemicals
Microbubble enrichment maintains cell health and physiology
The Mouse Naïve CD4+ T Cell Isolation Kit delivers a high purity population of murine Naïve CD4+ T cells that are ready for downstream use. The BACS™ Microbubble workflow is exceptionally gentle on cells, helping to maintain the health and physiology of Naïve CD4+ T cells during enrichment.
Mechanism of Action:The Mouse Naïve CD4+ T Cell Isolation Kit uses a negative selection method to remove unwanted cell populations and effectively enrich Naïve CD4+ T cells. Unwanted cells are labeled with an optimized cocktail of biotinylated antibodies targeting CD8a, CD11b, CD11c, CD19, CD24, CD25, CD44, CD49b, CD105, Gr1, Ter119, TCRγδ.
How it Works: The biotinylated antibody cocktail is added to the sample to label unwanted cells. BACS™ Microbubbles are added to the sample and bind to the antibody-labeled cells. Microbubbles bound to the undesired cells, quickly and gently float the undesired cells to the surface. Naïve CD4+ T cells, the cells of interest, are pelleted through centrifugation. Microbubble-bound cells and supernatant are easily aspirated away, leaving untouched and enriched Naïve CD4+ T cells healthy and ready for downstream use.

Key Features
The Mouse Naïve CD4+ T Cell Isolation Kit leverages Akadeum’s novel Buoyancy Activated Cell Sorting (BACS™) technology to deliver a highly enriched population of healthy, viable Naïve CD4+ T cells. BACS™ Microbubbles are fast, easy-to-use, and gentle on cells. The BACS™ Microbubble isolation platform minimizes handling by enabling single-tube processing, limiting unnecessarily loss of cells. The Naïve CD4+ T cell isolation protocol is fast and simple, taking just 30 minutes and not requiring magnets or columns. The result is a population of highly pure Naïve CD4+ T cells that are healthy and ready for downstream use.

Data
Untouched Naïve CD4+ T cells were isolated from splenocytes using the Mouse Naïve CD4+ T cell Isolation Kit (12210-150). Isolated cells were labeled with CD62L-PerCPCy5.5 and CD4-APCFire750. The fluorescently labeled cells were analyzed by flow cytometry. Debris and dead cells were excluded from analysis.
1. Can I do back-to-back isolation to improve purity?
Yes. This can be specifically helpful when using the Dead Cell Removal Microbubble Kit or the Human Red Blood Cell Depletion Microbubbles.
2. Which cell types can be processed using Akadeum’s Dead Cell Removal Microbubble Kit?
Akadeum’s Dead Cell Removal Microbubble Kit utilizes Annexin V-coated microbubbles to selectively bind phosphatidylserine, a marker exposed on the surface of cells undergoing apoptosis. This technology enables efficient removal of apoptotic cells across various cell types where apoptosis is actively occurring.
3. Can the Dead Cell Removal Microbubble Kit be used if the sample is under 35% viability?
Although the initial cell viability is below the recommended threshold, successful outcomes have been achieved by performing the protocol twice on such samples.
General Questions
Are Akadeum microbubbles hollow silica spheres?
Yes, Akadeum’s microbubbles are hollow silica spheres. Silica is a material that has extensive precedence for use in therapeutics and diagnostics.
Are antibodies directly attached to the microbubbles?
Only specific kits, such as our Dead Cell Removal (DCR) and RBC microbubble kits, use antibody-coated microbubbles. Most Akadeum microbubble products are not coated with antibodies; instead, a biotinylated antibody cocktail is provided to use with the streptavidin-coated microbubbles.
What is buoyancy-activated cell sorting (BACS)?
BACS is Akadeum’s proprietary cell separation technology that uses buoyant microbubbles to isolate specific cell populations utilizing only the power of gravity.
What are microbubbles?
Akadeum’s microbubbles are hollow silica spheres that are on average 12 microns.
How big are microbubbles?
Microbubbles average 12 um in diameter. Learn more about microbubbles technology.
How many cells can a microbubble lift?
Microbubbles can carry as many as four cells.
What is the Separation Buffer?
Ca2+, Mg2+ free Dulbecco’s PBS containing 2mM EDTA, and 0.5% bovine serum albumin (BSA). BSA must be biotin free to not interfere with kit performance.
After sitting in the refrigerator, all the microbubbles have separated out of solution. Is there something wrong?
No, this is normal due to the buoyant properties of microbubbles. The solution will need to be mixed well before every use. If processing multiple tubes, mixing between tubes is necessary.
I don’t have an aspirator/vacuum available in my lab, can I still use Akadeum microbubbles?
Aspiration is the best and easiest way to remove the microbubble layer after centrifugation. Pipetting off the bubble layer is not very effective. Vacuum pumps are available from a variety of vendors.
How are Akadeum’s kits shipped?
Kits are shipped on ice packs with overnight delivery.
