Human peripheral blood is one of the most easily accessible sources for obtaining unprocessed tissue and primary cells. At StemExpress’s Stem Cell Collection Centers, normal and diseased unprocessed human peripheral blood products are collected from IRB consented donors and shipped out directly to our customers or quickly processed at our FDA registered laboratory to ensure each primary cell type is of the highest quality. Each cell type is characterized by flow cytometry to guarantee our customers receive a pure and viable cell population for their research applications.

Frequently Asked Questions
Yes, we can source diseased blood upon specific request.
Yes, a donor is eligible to donate white blood cells every 4 weeks.
Usually around 8x109 PBMCs however, it will depend greatly on the way you process the Leukopak (Ficoll, RBC lysis, etc).
Yes, certain locations can receive same day courier delivery. We can also provide same day air shipments.
We can collect up to 250 ml into tubes.
Primary cells are very sensitive to many aspects of the thawing procedure, such as heat, DMSO, agitation, and high centripetal forces. Obtaining high viability after thawing human primary cells can be difficult if not performed quickly and with good laboratory techniques. At StemExpress, our laboratory technicians have years of experience handling and thawing frozen human primary cells and have designed a procedure that will help you obtain the highest viability of your cells.
