Please help me find antibodies to detect N-terminal (NC1) and C-terminal (NC2) domain of the type VII collagen. Merck offers several antibodies clone LH7.2, giving contradictory information about this clone:

MAB1345 - "Anti-Collagen Type VII Antibody, C-terminus, clone LH7.2 is an antibody against Collagen Type VII. Epitope C-terminus"

MAB1345-I-100UL - "Clone LH7.2 is a mouse monoclonal antibody that detects Collagen VII. It targets an epitope with in the central region of the N-terminal half".

Does anyone have experience using these antibodies? I would be grateful if you could tell me which antibodies specifically bind to C-terminus and N-terminus of Collagen Type VII.
