HUMAN NORMAL PB CD4+/CD45RA+/CD25- NAïVE T CELLS
Naïve T cells express the highest molecular weight isoform of CD45, CD45 RA. Those which express CD4 and are negative for CD25 are destined to become T helper cells. Naïve T cells have not yet been exposed to antigens.
PPA's Human Peripheral Blood CD4+/CD45RA+/CD25-Naïve T cells are isolated from peripheral blood mononuclear cells by negative immunomagnetic selection. All peripheral blood is collected from fully consented IRB approved donors that test negative for HIV, HBV and HCV.
