High-Quality PBMC: A Solid Foundation for Your Studies
Our highly trained CRO team specializes in the logistics, separation, and cryopreservation of functional PBMC in a regulated environment to support your preclinical or clinical studies, and we can serve as a central whole blood processing laboratory for multi-site studies.
Our optimized processes ensure exceptional cell functionality of cryopreserved PBMC for use in antigen-specific ELISPOT assays and storage.
Pioneers in Measuring Cell-Mediated ImmunityCTL was founded by pioneers in immunoassay development and analysis, and this deep expertise is evident in our CRO.
Our highly trained team performs a variety of assays in our regulated laboratory—whether to establish, perform qualification-validation, test samples to satisfy FDA requirements, or simply evaluate specimens for scientific significance.
Assays we perform include:
T Cell ELISPOT
B Cell ELISPOT
Neutralizing Antibody (Microneutralization Assays)
Cytometric bead array
Flow Cytometry and FACS
