JOKOH CO., LTD. was established in 1947 as a distributor of X-ray film and medical equipment. In 1964, we started to sell the cellulose acetate membrane, which was first developed by Fujifilm Corporation in Japan. The needs for the automation of the electrophoretic measurement increased as the electrophoresis using the cellulose acetate membrane became popular. For this needs, we first developed and sold the instrument, which automates the measurement of the optical density of stained protein on the membrane. By using this instrument, the time and effort for calculation of percentages in the fraction patterns was dramatically improved. In this post, we introduce the history of our research and development in automation of serum protein electrophoresis on the cellulose acetate membrane.
