摘要
1. Two new collagenous fragments were detected in great blue shark myocommata. 2. The fragments, isolated from pepsin digests, were shown to be sensitive to disulphide bond cleaving agents. The higher molecular weight fragment (designated HMW) of about 250 kDa gave rise to a 40 kDa fragment following reduction. The second fragment with a molecular weight of about 53 kDa (designated LMW) produced a major fragment of about 29 kDa after reduction with disulphide bond cleaving agents. 3. Type I collagen, a type I-like collagen and type V collagen were also detected in the myocommata.
