We investigated the protein extract of silkworm larvae. For the first time, an extract containing proteins from silkworm larvae, obtained by fractional precipitation using ammonium sulfate, was studied. As a result of experiment is established, that solutions of ammonium sulfate with a concentration from 20% to 65% are optimal for the sedimentation of protein molecules with a mass in the range of 25 and 45 kDa. Optimal results of the study proposed to use in the process of purification of recombinant proteins.
