[Effect of concanavalin A on the splenic lymphocyte proliferative activity of germ-free rats]. / Vliianie konkanavalina A na proliferativnuiu aktivnost' limfotsitov selezenki bezmikrobnykh krys.

Action of Con-A on the proliferative activity of spleen lymphocytes was studied using germfree and conventional Fisher rats 3-4 months of age and conventional 2-3 day old rats. The intensity of 3H-thymidine incorporation in lymphocytes of germfree and conventional animals was the same, however, the coefficient of stimulation was higher in germfree rats. Lymphocytes of suckling rats had a low reactivity to Con-A.

[Isolation of the basic myelin protein from guinea pig brain]. / Poluchenie osnovnogo belka mielina iz mozga morskoi svinki.

The modified method for obtaining encephalitogenic protein from the brain of a guinea pig with the use of gel filtration and ion-exchange chromatography is described. The electrophoretic mobility of the isolated protein is characterized and its molecular weight is determined.

[Isolation of monospecific antiserum to rat IgE]. / Poluchenie monospetsificheskoi antisyvorotki k IgE krysy.

Immunochemically pure IgE was obtained from the serum of LOW rats carrying IgE-plasmocytome by the immunochemical methods (ion-exchange chromatography and gel filtration). This IgE served as an antigen for immunization of a rabbit to produce a specific antiserum. The monospecificity of this antiserum was achieved by its sorption with normal serum proteins.
