LEGEND MAX™ Human IL-1α ELISA Kit with Pre-coated Plates

Interleukin-1 (IL-1) refers to two proteins, IL-1α and IL-1β, which are from different gene products. IL-1α and IL-1β share about 25% amino acid sequence identity. They are initially synthesized as 31 kD precursors, and then cleaved by proteases into mature proteins with molecular mass approximately of 17 kD.

IL-1 binds to both forms of the cell surface type I (IL-1RI) and type II (IL-1RII) IL-1 receptors. IL-1RI is expressed on T cells, fibroblasts, keratinocytes, endothelial cells, synovial lining cells, chondrocytes, and hepatocytes while IL-1RII is found on B-cell lineages, neutrophils, and bone marrow cells. Although both IL-1α and IL-1β are recognized by IL-1RI and IL-1RII receptors, IL-1α binds better to the type I receptor than IL-1β and vice versa.

IL-1 has different biological properties such as immunologic, pro-inflammatory, and protective effects. An increase of IL-1 by a variety of cells is a good indicator of infection by microbial toxins and inflammatory processes. It also affects B cell activation, immunocompetent cells and other immunologic cells. Studies show that the production of IL-1 has been detected in human joint fluids from patients with rheumatoid arthritis, osteoarthritis, traumatic arthritis, and psoriatic arthritis. In addition, IL-1α shows elevated levels in cancer such as colon cancer and cervical cancer.

The BioLegend LEGEND MAX™ Human IL-1α Sandwich Enzyme-Linked Immunosorbent Assay (ELISA) kit includes a 96-well strip plate that is pre-coated with a mouse monoclonal anti-human IL-1α capture antibody. The detection antibody is a biotinylated goat polyclonal anti-human IL-1α antibody. This kit is specifically designed for the accurate quantitation of human IL-1α from cell culture supernatant, serum, and plasma. It is analytically validated with ready-to-use reagents.
