Human peripheral blood CD4 Helper T Cells are isolated from peripheral blood mononuclear cells (PBMCs) using either POSITIVE or NEGATIVE immunomagnetic cell separation procedures
PBMCs are collected in HemaCare's FDA-registered collection centers following cGMP and cGTP collection guidelines from healthy human volunteer donors under IRB approved informed consent by leukapheresis using the COBE® Spectra Apheresis System MNC collection protocol. This mononuclear cell-rich leukapheresis product (LeukoPak) is extracted using continuous flow centrifugal technology directly into the collection bag. Mononuclear cells are purified using density gradient centrifugation techniques.
Serological and Infectious disease testing are performed with each donation. Customers should handle product as if potentially infectious following biosafety level 2 procedures.
