PROCESS FOR PURIFYING HIGH MOLECULAR WEIGHT HYALURONIC ACID |
摘要 |
A process for purifying high molecular weight hyaluronic acid from a biological source, including the steps of adjusting the pH of an aqueous solution containing high molecular weight hyaluronic acid from a biological source to a pH in the range from 1.7 to 3.3 and then diafiltering said aqueous solution at the same pH using a filter having a pore size in the range from 100,000 Daltons nominal molecular cut-off to 0.45 m, and of removing cells from the aqueous solution containing high molecular weight hyaluronic acid from biological source.
