Charles River human CD3+ T cells are isolated from fresh leukopaks using either positive immunomagnetic cell separation techniques (negative selection also available), and are then cryopreserved using CryoStor CS10 media and stored in vapor phase liquid nitrogen. The CD3+ T cells are tested post-thaw to ensure high cell yield, viability, purity, and quality.

• Rigorous donor screening and product QC testing to ensure consistent CD3+ T cell lots for discovery and therapeutic development
• Guaranteed post-thaw viability ≥90% as tested by NucleoCounter NC-200™
• Guaranteed post-thaw purity ≥90% as tested via flow cytometry
• Guaranteed CD3+ T cell yields post thaw as listed per vial size
• Fill volume is 1mL of CD3+ T cells in a 2mL vial size
• Full donor screening (serology and infectious disease panel)
• Isolated from fresh leukopaks that are collected from healthy human donors that have consented under an IRB approved protocol
