Akadeum’s Human CD4+ T Cell Isolation Kit delivers a high-purity population of human CD4+ T cells that are ready for downstream use. Use of these microbubbles to enrich human PBMC samples for CD4+ T cells prior to flow sorting can greatly reduce final sort times, helping to isolate more cells for better science. Akadeum’s microbubble workflow is exceptionally gentle on cells, helping to maintain the health and physiology of immune cells during enrichment.
Mechanism of Action: Akadeum’s Human CD4+ T Cell Isolation Kit uses a negative selection method to remove unwanted cell populations from the sample, effectively enriching for the T cells of interest while maintaining cellular physiology. The undesired (non-CD4+ T) cells are labeled with Akadeum’s optimized cocktail of biotinylated antibodies targeting CD8, CD11b, CD14, CD16, CD19, CD36, CD56, CD123, CD235a, and TCR-γδ. Streptavidin-coated microbubbles are then mixed into the sample, binding to the labeled cells and floating them to the top of the sample container for removal.
How it Works: First, Akadeum’s biotinylated antibody cocktail is added to the sample to label the contaminating cells. Next, the microbubbles are mixed into the sample where the seek out and bind to the unwanted cells. Once bound, they quickly and gently float the undesired cells to the surface. An optional centrifugation step pellets the CD4+ T cells, and the microbubbles, microbubble-bound cells, and supernatant are easily aspirated away leaving the untouched and enriched CD4+ T cells happy, healthy, and ready for downstream use.
