We are specialized in immune monitoring of CMI with emphasis on T and B cell (e.g. antigen specific plasma B cell and antibody producing memory B) evaluations within pre-clinical and clinical studies. Thanks to our in-house expertise and rigorous procedures, we can conduct all assays including ELISPOT, ELISA, NAb, NK- killer assay, CBA, FACS, proliferation, and our regulated laboratory—whether to establish, to perform qualification-validation, test samples to satisfy FDA requirements or simply evaluate specimens for scientific significance.

We provide comprehensive solutions for PBMC sample processing: Serving as central whole blood processing laboratory with optimized logistic, separation of PBMC, cryopreservation to ensure exceptional cell functionality of cryopreserved PBMC in the antigen specific ELISPOT assay and storage.

Our GCP, GLP regulated laboratory is as well CLIA/CLEP certified/approved, Part 11 compliant, specializes in custom client Laboratory Developed Tests (LDT) in accordance with FDA guidance for Bioanalytical Method Validation; and capable of processing up to 450 samples per week.
