The ELISPOT assay is the most sensitive technique available for the detection of immune cells which secrete specific signature proteins such as antibodies or cytokines.
Plaque and Colony Counting
The CTL BioSpot® platform contains a wide range of automated image capture and analysis systems for microbial and mammalian colony formation assays.
T Cell Monitoring with PBMC Samples
CTL's cryopreserved peripheral blood mononuclear cells (PBMC) are ideally suited for T cell monitoring in ELISPOT and ELISA assays, cytokine bead arrays, tetramer and pentamer staining, cytokine capture assays, and any assays that require live PBMC.
Serum-free Cell Culture Media
Serum-free cell culture media allow users to standardize their cell culture conditions by avoiding the use of undefined and highly-variable serum products derived from humans or animals, e.g. human AB serum or fetal calf serum (FCS).
