Anti-antihemocytic serum and a method for the preparation thereof

摘要

The anti-antihemocytic serum comprises water-soluble proteins in a physiological solution isolated from cells of the bodies of insects immunized by a single injection in a dose of 0.25 mu l to 2.0 mu l for every insect with the anti-hemocytic serum produced from the plasma of the blood of an animal immunized with a suspension of hemocytes from cells of the bodies of the given species of insects. The titre of hemocytoagglutinins of the anti-antihemocytic serum is 1:256 to 1:1024. The method for the preparation of anti-antihemocytic serum resides in immunizing the given species of insects with antihemocytic serum, produced from the plasma of the blood of an animal immunized with a suspension of hemocytes from cells of the bodies of insects, by means of a single injection in a dose of 0.25 to 2.0 mu l for every insect, removing the hemolymph and the alimentary tract from insects in 24 hours, homogenizing the remaining cells of the bodies of insects and diluting them with a physiological solution, isolating proteins from cells of the bodies of insects by breaking the integrity of cells, and isolating the fluid from the resultant mixture separating it from the indissoluble portion of cells of the bodies of insects, obtaining the target product.
