Monocytes make up between three to eight percent of the leukocytes in the blood. Monocytes migrate from the bloodstream to other tissues and then differentiate into macrophages or dendritic cells. Monocytes and their macrophage and dendritic cell progeny serve three main functions, namely phagocytosis, antigen presentation, and cytokine production, in the immune system.

PPA's Human Normal Peripheral Blood CD14+ Monocytes are isolated from peripheral blood mononuclear cells by either positive or negative immunomagnetic selection, depending upon your needs. All peripheral blood is collected from fully consented IRB approved donors that test negative for HIV, HBV, and HCV.
