CD45RA is an isoform of tyrosine phosphatase CD45 (leukocyte common antigen) that is expressed on different leukocytes including naive and resting T cells, B cells as well as monocytes. Creative Bioarray's Human CD4/CD45RA Cell Isolation Kit has been developed to isolate highly purified human CD4/CD45RA cells from peripheral blood mononuclear cells (PBMCs). The label-free target cells with up to 90% purity are immediately available for downstream applications such as flow cytometry, culture, or cell-based experiments.
