Fully-functional PBMC at your fingertips™

A library of genetically and immunologically characterized white blood cells

CTL offers a library of presently 400+ donors’ PBMC that have been cryopreserved to maintain their full functionality, hundreds of aliquots from each subject. You therefore may repeat and expand experiments using the same cells, “indefinitely”. These ePBMC have been characterized with respect to their T- and B-cell reactivity to SARS-CoV-2, HCMV, EBV, influenza, and other common recall antigens. Such cells are indispensable for antigen-specific T and B cell ELISPOT/FluoroSpot assay development and validation, as well as proficiency testing, with all of which CTL can assist. Entire studies can be conducted with these cells. Need a cohort of HLA-allele-matched donors? Interested in any other allele? We have dozens of subjects for most alleles at your fingertip, no IRB needed!
