Invitrogen
Some class-specific anti-collagens are specific for three-dimensional epitopes, resulting in diminished reactivity with denatured collagen or formalin-fixed, paraffin embedded tissues. This antibody reacts with most mammalian Type I collagens and has negligible cross-reactivity with Type II, III, IV, V or VI collagens. Cross-reactivity with other human serum proteins and non-collagen extracellular matrix proteins is neglible.|Western blot: this preparation results in a native conformation of the protein. It is recommend not to add 2-ME or DTT in lysis buffer and not boiling the sample.
Collagen I is a Type I collagen with a triple helix structure comprised of two alpha-1 chains and one alpha-2 chain. Collagen I is a member of group I collagen (fibril-forming collagen) found in most connective tissues, and is abundant in bone, cornea, dermis and tendon. Mutations in the COL1A2 gene encoding the alpha-2 chain are associated with osteogenesis imperfecta types I-IV, Ehlers-Danlos syndrome type VIIB, recessive Ehlers-Danlos syndrome Classical type, idiopathic osteoporosis, and atypical Marfan syndrome. Symptoms associated with mutations in the COL1A2 gene which codes for the alpha-2 chain, however, tend to be less severe than mutations in the COL1A1 gene, reflecting the different role of alpha-2 chains in matrix integrity. Reciprocal translocations between chromosomes 17 and 22, where Collagen Type 1 genes and the gene for platelet derived growth factor beta are located, are associated with a particular type of skin tumor called dermatofibrosarcoma protuberans, resulting from unregulated expression of the growth factor. Two transcripts, resulting from the use of alternate polyadenylation signals, have been identified.
