Immunogen Human type I collagen (Sigma-Aldrich, C5483), digested with Collagenase from Clostridium histolyticum (Sigma-Aldrich, C0773)
Clone 2G8
Isotype IgM
Specificity This antibody, compared to collagen type 1, preferentially recognizes Collagenase-digested Human type I Collagen. There is some cross reactivity with Human epidermal keratinocytes. No cross reactivity has been detected with Mouse Collagen. In immunoblotting (not reducing conditions), the antibody reacts with both intact as digested collagen type 1. The antibody doesn't cross react with Human type IV Collagen.
Cross-Reactivity (Details) Species reactivity (tested):Human.
Purification Ammonium Sulphate precipitation and DEAE Chromatography
Background Collagens play a dominant role in maintaining the structural integrity of organs and tissues (1), but they also regulate cell polarity, migration, survival and phenotype, and provide diffusible signaling molecules following breakdown (2). Within the family of collagens that currently comprises 21 members, type I collagen is included in the group of fibril-forming collagens based on its structural and functional features. Type I collagen is ubiquitous in all vertebrates and is among the largest and most complex of all macromolecules. It accounts for 80-90 % of all collagenous proteins in skin (3). The helical trimeric molecules of type I collagen compromise two α1(I) chains and one α2(I) chain, encoded by two separate genes Col(I)α1 and Col(I)α2, respectively (3). Matrix metalloproteinase (MMP)-1,-8, -13 and -14 cleave the peptide bonds between residues Gly775 and Ile776 of the α1(I) chain and Gly775 and Leu776 of the α2(I) chains, resulting in 1/4 and 3/4 fragments.Synonyms: Alpha-1 type I collagen, Alpha-2 type I collagen, COL1A1, COL1A2
