In Western blotting (but not ELISA), MAB8887 recognizes both a1(II) and a3(XI) chains which have identical primary structure. In Western blotting, MAB8887 reacts with the TCA fragment of lathyritic type II collagen after digestion with mammalian collagenase. It also reacts with pepsin-digested type II collagen. It will not react with intact Collagen II under traditional conditions.

Its epitope is localized in the triple helix of type II collagen. It shows no cross-reaction with type I or type III collagen. Immunoblotting of CNBr peptides of collagen II shows that MAB8887 reacts with CB11 (25kDa) fragment which is the site of immunogenic and arthritogenic epitopes along the intact type II molecule.

In pepsin solublized collagen II, MAB8887 reacts with a 95-97 kDa fragment, as well as, the native single chain of 120kDa. If propeptides are present, MAB8887 will detect a 200kDa fragment.


Purified type II collagen; obtained from adult chicken sternum by limited pepsinization.

Western Blot (Mayne, 1994)

Immunohistochemistry (Formalin/Paraffin): 1-2 μg/mL, 30 minutes at room temperature. Staining of paraffin embedded tissues requires digestion of tissue sections with pepsin at 1mg/mL in Tris HCl, pH 2.0 for 15 minutes at RT or 10 minutes at 37ºC.



Optimal working dilutions must be determined by end user.
