$479.00Add To Cart
Type I Collagen usually exists as a heterotrimer formed by alpha 1(I) and alpha 2(I) chains and is found in bone, cornea, skin and tendon. In foetal tissues also homotrimers of alpha-1(I) are found, but they are not constituents of normal adult tissues. Collagens consist of a family of highly specialized glycoproteins of which at least 16 genetically distinct types are known to date. The basal unit of a collagen molecule consists of a triple-helical structure formed by 3 alpha-chains. Predominant amino acids are glycine, proline and hydroxproline. Regularly also lysines and hydroxylysines occur, which are responsible for cross-linkage and glycosylation of the protein chains. Different composition of alpha-chains and different glycosylation contribute to the high variability of collagens in different tissues and organs. Human collagen type I, cross-reactivity with collagen type II and IV <0.1%, collagen type III and V <1.0%, human fibronectin and laminin <0.1%, mouse laminin <0.1% (RIA at a 1:500 dilution).

IHC(P), IFA, ELISA, RIA, IB/WB
Incubation Time: IHC(P) 60 min at RT or 2-8°C over night
Working Concentration: (purified, lyophilized) IFA 1:80, IHC(P) 1:200 - 1:600, ELISA >1:200 (OD>500)
Pre-Treatment: After de-waxing the tissue slices they are treated with 0.2% hyaluronidase (app. 300 U/mg e.g. Art. No. HYA02-50) in TBS 15 min at 37°C. Thereafter non-specific binding is blocked by blocking serum or 3% BSA in TBS. For peroxidase systems blocking with 1% peroxide solution in TBS for 30 min at RT is recommended.
Positive Control: Human skin
