With personalized service, custom products, flexible delivery times, and the option to reserve entire lots to prescreen cells for applications, we help you get the cells you need. Isolated using negative immunomagnetic separation techniques and characterized by surface markers CD8+, CD45RA-, and CD45RO+, cells are collected using Institutional Review Board (IRB)-approved consent forms and protocols and cryopreserved in animal component-free CryoStor®CS10 medium. Additional documentation to meet institutional requirements and high-resolution HLA typing (Class I and Class II alleles and CMV status) is available upon request. Acid-citrate-dextrose solution A (ACDA) is added during collection as an anticoagulant. Contact techsupport@stemcell.com for donor specifications (BMI category, smoking status, ethnicity, etc.). Donors are screened for HIV-1, HIV-2, hepatitis B, and hepatitis C. Certain products are only available in select territories.
