Genetic Analysis of Basic Chymotrypsin Inhibitors in the Hemolymph of the Silkworm, Bombyx mori

Abstract

Using an acidic polyacrylamide gel electrophoresis followed by activity staining, three basic chymotrypsin inhibitors have been found in larval hemolymph of the silkworm, Bombyx mori. These components, named CIs-b1, b2 and b3 in order of migration towards the cathode, were subjected to linkage analysis. Results indicated that the genes coding for CIs-b1 and b2 were found to be novel multiple alleles of the Ict-H locus linked with the Y gene on the second linkage group.
