MACS MicroBeads

Untouched isolation of human and mouse T cells and T cell subsets in only 18 minutes

T cell isolation kits

Updated CD4 and CD8a MicroBeads, mouse allow for positive selection of T cells in only 13.5 minutes

T cell isolation directly from blood products

StraightFrom™ MicroBeads allow magnetic cell separation directly from human blood products, such as whole blood, buffy coat, or leukoreduction system chambers (LRSCs). CD4+ and CD8+ T cell subsets can be purified using the autoMACS® Pro Separator, the MultiMACS™ Cell24 Separator Plus, or manual separators.

Isolation of cytokine-producing T cells

Cytokine Secretion Assay – Cell Enrichment and Detection Kits are designed for magnetic enrichment and highly sensitive detection of cytokine-secreting cells. This unique technology enables detection of one antigen-specific T cell per million cells. Isolated cells can be immediately used for downstream applications, e.g. cell culture and flow cytometric analysis.
