Abstract
1. 1. Using two silkworm strains selected from various electrophoretic variants, five haemolymph chymotrypsin inhibitors were partially purified and their properties were compared. 2. 2. Five inhibitor fractions separated on DEAE-Sephacel and Ultrogel AcA54 columns corresponded to the electrophoretic bands; these were classified into two groups, comparatively high, 39,000 (c and d) and low molecular weights, 5500–8500 (a, e and g). 3. 3. Inhibitor a was extremely heat stable, e and g were also stable considerably, but c and d were labile. 4. 4. Ouchterlony's double diffusion test showed that the inhibitors c and d are immunologically identical whereas no precipitate was observed between inhibitors a, e, g and anti-d serum.
