That protein is transferred from the aqueous phase into reversed micelles and then transferred from reversed micelles into aqueous phase is called reversed micelle extracion. Reversed micelle extraction is a relatively new separation technique that has recently received much attention for the recovery of proteins. The effect of pH value of water phase and ionic strength on the Puification of BSA by CTAB-octanol-CHCl_3 reversed micelles was investigated and the best condition for purification was found and v...
