Isolation of low molecular protein P-9 from nuclei of NK/Ly lymphoma and Guerin carcinoma.

ABSTRACT

Protein with molecular weight 9000 (protein-9) was found in nuclei of resting cells of NK/Ly lymphoma and Guerin carcinoma by electrophoresis in polyacrylamide gel. Method of preparative isolation P-9 concluding in fractionation of nuclei from phenol extract by acetone at different pH and following electrophoresis in polyacrylamide gel was made. Electrophoretically homogeneous preparation of protein P-9 from nuclei of NK/Ly lymphoma and Guerin carcinoma was obtained.
