Type IV Collagen is a non-fibrillary network of different alpha-chains: alpha 1(IV) to-alpha 6(IV). It is typically found in basal membranes of different organs (e.g. skin, lens, lung, kidney). 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 IV 100%; human collagen I, II <0.1%; human collagen III, V <1.0%; human fibronectin < 0.1%; mouse laminin < 0.1% (RIA at 1:10000 dilution).

Secondary Reagents: Anti-rabbit IgG-conjugates, e.g. anti-rabbit IgG:FITC (Art. No. FI-1000) or anti-rabbit IgG:DyLight488 (Art. No. DI-1488).
Concentration: app. 1 mg/ml
Species Reactivity: Human
IHC(P), IFA, ELISA, RIA
Incubation Time: IHC(P) 60 min at RT or 2-8°C over night
Working Concentration: (purified, lyophilized) IFA 1:80, IHC(P) 1:500 - 1:1000
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, placenta or lens capsule
