Even though CTL’s Uncharacterized PBMC (UC-ePBMC^®) did not undergo the extensive genetic and immunological characterization as our Characterized PBMC, they still offer major advantages over blood draws obtained from uncharacterized donors. These include:

QC: Each batch has undergone thorough quality-control, making sure that the viability and functionality of each vial after thawing approximates that of freshly isolated PBMC. Each vial of UC-ePBMC^® contains at least 10 million viable cells with less than 10% post-thaw dead cells.

Low-background, high-signal: Each batch has been selected for low-background activity and frozen serum-free, making sure that cellular assays performed with UC-ePBMC^® cells provide results with high-signal to noise ratios.

Consistency: From each donor we freeze batches with hundreds of vials, with each batch functioning indistinguishably from each other. Therefore, unlike regular blood draws of your own where infections and environmental influences can adversely affect the PBMC’s performance, even when drawn at different time points from the same donor, ePBMC^® give you the opportunity to work with the very same cell material experiment after experiment, over and over. If this reproducibility is important for you, simply let us know! We can reserve cells of the same lot for you! 

No hassle: UC-ePBMC^® have been ethically collected for you and can be used as common reagents, no IRBs needed because we’ve taken care of that for you. It takes a fraction of the time and effort to thaw and prepare ePBMC^® for a bioassay compared to collecting blood and performing Ficoll^® separation.  

Minimized infectious risk: All ePBMC^® donors have been screened for common infections, and were found to be negative for:

• HIV 1/2 Antibody 
• HTLV I/II Antibody 
• Hepatitis B Surface Antigen 
• HCV Antibody 
• Hepatitis B Core Antibody 
• Serologic Test for Syphilis 
• NAT HIV/HCV 
• NAT WNV  

Are you looking for PBMC with certain HLA type or T cell reactivity? If so, please view our Characterized CTL C-ePBMC^® Library™.

Are you interested in PBMC with unique genetic or functional properties? The CTL ePBMC^® Sample Set™ provides convenient access to PBMC from a high number of donors that you can screen for the traits of your interest, selecting those that meet your needs best.  

Would serum antibodies help you identify PBMC of your interest? We collect plasma from all ePBMC^® donors that you can screen for the presence of antibodies, see the CTL Plasma Sample Set™.

Shipping and Handling are additional unless otherwise specified. Pricing is for USA and Canada only. All others, please inquire for the subsidiary in your region. PBMC, thawing solutions, and ready-to-use peptide solutions are shipped frozen on dry ice in thermo-isolated Styrofoam packaging or in dry cryoshippers on LN₂ vapors.
