Abstract

1 Amarked streaming-birefringence was found in the aqueous extract of the arm muscle of the squid, while none in that of the mantle muscle.<br> 2 On electrophoretic analysis, both arm and mantle extracts showed patterns consisting of 3 components. However, the values of the electrophoretic mobility suggest that the slower two components of the arms correspond to the faster two of the mantle, and that the fastest component of the arms is responsible for the streaming-birefringence.<br> 3 The mobility values of the components were found to increase slightly after frozen storage.<br> 4 The nature of the streaming-birefringent protein has been discussed, existence of a protein but myosin or actomyosin being suggested.
