ImmunoSpot® Applications


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 & 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).
