The fibroin proteins directly extracted from silk glands of Bombyx mori were used for polyacrylamide gel electrophoresis in th presence of sodium dodecyl sulfate (SDS-PAGE). The subunit structure of fibroin molecule was discussed. It has been elucidated that the native fibroin molecule consists of subunits a,b and c with molecular weights of 280 kD, 230 kD and 25 kD, respectively, Since the amount of them is much more than that of the b subunit, the a and b subunits are the major component of fibroin. Of which the b subunit is composed of smaller e subunit of M_w about 130 kD and f subunit of M_W about 125 kD,linked by disulfide bonds.
