Detection of the α2 chain. Immunostaining was conducted on cross- (A, D, H, K, O, S and W) and transverse (B, E, I, L, P, T and X) sections of skeletal muscle. Blots containing reduced and non-reduced sets of lysates from cells expressing α1, α2 and α3 chains individually (C, F, J, M, Q, U and Y) were probed with each α2 antibody. Blots containing multimeric collagen VI expressing all three chains and electrophoresed under non-reducing conditions were probed (G, N, R, V and Z). Migration position of molecular weight markers (in kDa) is shown
