Polyglycolic acid solubility
PLGA, PLG, or poly(lactic-co-glycolic acid) is a copolymer which is used in a host of Food and Drug Administration (FDA) approved therapeutic devices, owing to its biodegradability and biocompatibility. PLGA is synthesized by means of ring-opening co-polymerization of two different monomers, the cyclic dimers (1,4-dioxane-2,5-diones) of glycolic acid and lactic acid. Polymers can be synthesize… WebRecipe. 1.Add 1ml of 0.1% Diethylpyrocarbonate (DEPC) to 1000ml distilled water. 2.Mix well and let set at room temperature for 1 hour. 3.Autoclave. 4.Let cool to room temperature prior to use. 这有帮助吗？. 是 否 第一个投票!
