Anti-Collagen antibodies have been used for indirect trapping ELISA for quantitation ofantigen in serum using a standard curve, for Immunoprecipitation and for native(non-denaturing, non-dissociating) PAGE and Western blotting for highly sensitivequalitative analysis. Recommended Dilutions: ELISA 1/5,000-1/20,000. Western blot: 1/500-1/5,000. Immunoprecipitation: 1/100. Immunohistochemistry: 1/50-1/200 (prepare tissues as frozen tissue sections). Note: This product was assayed by Immunoblot and found to be reactive against CollagenIV at a dilution of 1/5,000-1/10,000. This product was also assayed against 1.0 μg of Collagen IV in a standard sandwich ELISAusing Peroxidase conjugated Affinity Purified anti-Rabbit IgG [H&L] (Goat) (Cat#R1364HRP)and (ABTS (2,2'-azino-bis-[3-ethylbenthiazoline-6-sulfonic acid]) as a substrate for 30 minutes at room temperature. A working dilution of 1/4,000-1/8,000 of the stock

Collagens are highly conserved throughout evolution and are characterized by an uninterrupted "Glycine-X-Y" triplet repeat that is a necessary part of the triple helical structure. For these reasons it is often extremely difficult to generate antibodies with specificities to collagens. The development of type specific antibodies is dependent on NON-DENATURED three-dimensional epitopes. Collagens were extensively purified for immunization from human and bovine placenta and cartilage by limited pepsin digestion and selective salt precipitation. This preparation results in a native conformation of the protein. Antibodies are isolated from rabbit antiserum and are extensively cross-adsorbed by immunoaffinity purification to produce 'type' specific antibodies. Greatly diminished reactivity and selectivity of these antibodies will result if denaturing and reducing conditions of SDS-PAGE and immunoblotting are used.Synonyms: COL4A1
