StemExpress is a life-science company dedicated to supporting researchers and clinicians globally by offering high-quality IRB-consented human tissues and primary cells from bone marrow, cord blood, peripheral blood (healthy or diseased), mobilized peripheral blood, and maternal blood. Samples are collected from our strategically located Stem Cell Collection Centers or within our vast network of partnering hospitals by our skilled procurement staff. Whole samples are sent directly to our clients or quickly processed to a primary cell population at one of our on-site GLP regulatory-compliant laboratories. We streamline the entire workflow, from donor recruitment all the way to shipping the final product, guaranteeing every sample arrives with the highest purity, viability, and quality researchers and clinicians need to ensure confidence in their results.

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.
