An ELISA or Enzyme-Linked ImmunoSorbent Assay, is a widely employed biochemical technique used to detect and quantify secreted or intracellular protein concentrations within a variety of different sample types including but not limited to sera, cell lysates, and plasma. There are typically three different types of ELISAs – all of which are performed in a microplate: direct, indirect, competitive, and sandwich. Assay Biotech offers a variety of ELISA formats that can detect any target antigen ranging from intra-fluid cytokines to cell-specific modified proteins via colorimetric and fluorogenic readout methods.

Assay Biotech currently provides the following types of immunoassay Kits:

• ● Cytokine and Growth Factor Sandwich ELISAs
