| Abstract: | A simple method is suggested for the preparative isolation of native albumin in the thick (6 mm) block of the agar-agar gel on the veronal-medinal buffer solution (pH 8.6, ionic strength 0.1). The method is based on the analytical horizontal electrophoresis. 0.8-1 ml of 10% solution of proteins was introduced into each of two starting trenches. 5h after the beginning of distillation in the anode edge of the plate at a distance of 35 mm from the start two collector slits were cut out perpendiculary to the protein movement. Then they were filled with the NaCl physiological solution and protein portions were taken thrice each half an hour. The purity of albumins was checked immunologically. The method may be applied for obtaining other individual proteins. |
