Abstract

|
|
The male and female muscle of the 16 major bands in the protein patterns of the tissues of the mud-snail, Cipangopaludina chinensis malleata, were almost similar, and the bands E (Mr. 41,500), H (Mr. 52,100), L (Mr. 71,700), N(Mr. 98,500), O (Mr. 107,900) and P (Mr. 112,900) had the same molecular weights which appear in the muscles, testis and ovary. But it showed that the testis and the ovary had their characteristic patterns, and it was also observed that, besides the bands common to all tissues, the bands which appear both in the testis and the ovary are about five: the bands d (Mr. 15,600), k (Mr. 37,100), p (Mr. 57,000), s (Mr. 80,300), and v (Mr. 105,400). The result of the amino acid analysis showed that the quantity and composition of amino acid appeared, as the protein pattersn did, in the order of ovary, muscles and testis. This reveals that in the ovary a great quantity of protein which appears in the whole body was investigated, while the testis contained only little protein due to the phenomenon of morphogenesis in which sperms were developed through the condensation of the nuclei.
