Primary T-Cell Functional Assays

T-cell based immunotherapy strategies have become increasingly important in disease treatments that harness the human immune system. LakePharma offers a variety of assays for characterizing T-cell activity with candidate antibodies.

    1. T-cell activation and proliferation assays include stimulation with staphylococcal enterotoxin B (SEB), cytomegalovirus (CMV) recall antigen, and anti-CD3 antibodies.

    2. Assay readouts include cytokine measurement by ELISA or FACS.

    3. T-regulatory suppression assays.
