Human peripheral blood CD8+CD45RA+ na�ve cytotoxic T cells from Creative Bioarray are enriched by means of negative selection. Cells expressing CD4, CD14, CD16, CD19, CD20, CD36, CD45RO, CD56, CD57, CD94, CD123, CD244, TCR?/?, and glycophorin A are depleted from the mononuclear cell population using immunomagnetic particles leaving purified, untouched CD8+CD45RA+ na�ve cytotoxic T cells.
