High-Throughput Immune Contract Laboratory Services

By CTL Laboratories

A four to five week turnaround time for up to 1,000 subjects assayed for antigen-specific cytokine responses allows you to significantly accelerate immune monitoring of patient samples.


Cellular Technology Limited (CTL) has many years of experience in performing contracted laboratory services. Our laboratory complies with CLIA and FDA regulations (21 CFR Part 58 and 21 CFR Part 11). CTL's greatest strength lies in its high-throughput T cell monitoring capabilities and world-class ELISPOT (Enzyme-Linked ImmunoSpot® Assay) expertise. We can offer a four- to five-week turnaround time period for processing, testing, and data analysis of up to 1,000 specimens.

Our GLP Laboratory's high throughput capability allows you to significantly accelerate the development process for drugs and vaccines entering the clinical testing phase, as well as subsequent immune-monitoring of patient samples.

Thanks to CTL's in-house expertise, we can conduct all Cell-based Immune Monitoring assays (with an emphasis on T cells) in a GLP-compliant manner. We can develop and validate test methods to suit your needs and accommodate FDA requirements. CTL specializes in high-throughput Immune Monitoring: from specimen processing to data acquisition, analysis, and quality control.

ELISPOT assays and the related multiplex FluoroSpot technology are ideal for measurements of specific per-cell cytokine production and direct ex vivo cytotoxicity assays. Testing of T cells for simultaneous secretion of multiple cytokines indicating the presence of polyfunctional T cells, T cell functional avidity studies and epitope mapping, and B cell ELISPOT assays for determining the class or subclass of antibody-secreting cells, are just a few areas where ELISPOT and FluoroSpot are used.

CTL Laboratories has on-site facilities for processing whole blood, PBMC isolation, and cryopreservation of lymphocytes for later functional assay testing -- allowing us to act as a central processing facility for multisite studies. We are fully equipped to handle the logistics of collection, processing, cataloging, and cryo-storage of samples from multiple clinical collection sites.
