ABSTRACTMyocommata and endomysium fractions were prepared from the different parts of body muscle of carp and spotted mackerel. Both type I and V collagens were detected in the myocommata and endomysium fractions of both fish. The relative concentration of type V collagen to type I collagen was higher in the endomysium fraction than in the myocommata fraction. Both type I and V collagens were less soluble in the endomysium fraction than in the myocommata fraction. These results indicated that the biochemical property of the collagen in the pericellular connective tissue was different from that of the collagen in the interstitial connective tissue of fish.
