Alport syndrome is an inherited disease characterized by the pathological absence or reduction of the collagen α5(IV) chain in glomerular basement membrane (GBM), tubular basement membrane (TBM) and Bowman's capsular basement membrane. Anti Collagen 4 (ALPHA)2(IV) mAb (Clone H25, Texas Red) (cat no. SGE-CFT425) is one of three different rat mAbs included in Anti-Collagen 4 Cocktail mAb (Clones H53, B51, H25) (SGE-CFT45325) for easy and rapid staining of human renal and skin biopsy sections to distinguish Alport syndrome from normal tissue. Anti-Collagen 4 Cocktail mAb (Clones H53, B51, H25) comprises two different FITC-conjugated mAbs (clones H53 and B51) that reveal the Alport-affected α5(IV) chain in glomerular, tubular and Bowman's capsular BMs and an internal positive control Texas Red-conjugated mAb (clone H25) that targets α2(IV) to reveal endothelial basement membrane structure
