Abstract: | Brevin or plasma gelsolin, a calcium dependent actin-binding and actin-severing protein, was purified from bovine plasma by a very rapid and simple procedure; ammonium sulfate fractionation and only one step of anion exchange column chromatography by a convenient use. It takes only 24 hrs to complete all the procedure. The purity of brevin prepared by this method was more than 95% on SDS-PAGE and total recovery was much better than previous preparation methods. This brevin preparation has about 8 isomers on 2-D PAGE and strong severing activity on F-actin under electron microscopic observation. |
