This antibody (clone 2139) recognizes the conformational J1 epitope on the triple-helical structure of the native Collagen Type II molecule. The J1 epitope on mouse collagen consists of residues 551–564. It cross-reacts with mouse, rat, human, bovine, and chicken.
Collagen type II, encoded by the COL2A1 gene, is a crucial component of cartilage and plays a vital role in maintaining joint integrity. In mouse models of arthritis, such as collagen-induced arthritis, COL2A1 is studied for its role in cartilage degradation, a key feature of conditions like rheumatoid arthritis and osteoarthritis. Research on COL2A1 helps in understanding arthritis mechanisms and developing new treatments.
Synonyms:
Collagen alpha-1(II) chain, COL2A1, Collagen Type II, Collagen Type 2, CII.
M2139 binds to the triple helical J1 epitope on collagen II. Binding to collagen II epitopes was determined in bead-based flow immunoassay as median fluorescence intensity (MFI). Triple helical (Gly-Pro- Hyp)x11 is a synthetic control peptide with 11 repeats of the Gly-Pro-Hyp sequence and mimics the collagen II backbone structure.
