Type I Collagen (Human) Staining Kit
Rat monoclonal antibody, 42R (IgM) is highly specific to human type I collagen and does not cross-react with other species of type I collagen, and ideal for staining type I collagen in human tissues.
Type II Collagen (Species of Common) Staining Kit
The four clone monoclonal antibody cocktail (Arthrogen-CIA®) to type II collagen recognizes the conserved epitopes of various species of type II collagen, such as human, monkey, porcine, rat, mouse, rabbit, equine, and chick, and cross-reacts to all species to type II collagen by more than 95%. Thus, this cocktail can be used for immunoblotting and immunostaining of tissue sections from these species.
Note: Since alpha3 (XI) chain of type XI collagen is identical to alpha1 (II) chain of type II collagen, these monoclonal antibodies cross-react to type XI collagen, but do not cross-react to type I, type III, or type IX collagen.
Type IX Collagen (Multi - Species) Staining Kit
The monoclonal antibody cocktail to type IX collagen recognizes the conserved epitopes on the low molecular weight fragment of human, bovine, rat, mouse, and chick type IX collagen. Thus, this cocktail can be used for immunoblotting and immunostaining of type IX collagen in tissue sections from human, bovine, rat, mouse, and chick.
Note: These anti-type IX monoclonal antibodies do not cross-react to type I, type II, and type XI collagen. The cross-reactivity of type IX in other species (except human, bovine, rat, mouse, and chick) has not been determined.

Type IV Collagen (Glomerular Basement Membrane) Staining
Rat nephritogenic monoclonal antibodies, clone a84 (Catalog # 7061 and 7062) and b35 (Catalog # 7062 and 7064), can be used for immunostaining of rat kidney basement membrane. These monoclonal antibodies specifically recognize the NC1 fragment of rat type IV collagen of glomerular basement membrane. See Rat Glomerular Nephritis.
Chondrex also provides mouse monoclonal antibodies, Clone 3-1-1 (Catalog # 7056, and 7057) and Clone CB243 (Catalog # 7058 and 7059), which recognize the conserved epitopes on the NC1 fragment of mouse and bovine type IV collagen. These monoclonal antibodies are not capable of inducing nephritis in mice, and have been used for immunoblotting.
