Enzyme-Linked ImmunoSorbant Assay is a quantitative and sensitive assay which quantifies substances such as antibodies, hormones, proteins and peptides even in a complex matrix such as serum or cell homogenate. Applications include RadioImmuneAssay (RIA) for small molecules and ELISPOT, which detects signals (e.g. cytokine) from a single cell. Our scientists have decades of experience developing these methods, even at pg/mL levels in a complicated matrix such as serum, with detection levels of 1 part per 10 million.
