活性酯PEG(MPEG-NHS)是能與氨基(-NH2)反應(yīng)的PEG衍生物,可以用來修飾蛋白質(zhì),多肽和其他任何帶有氨基基團(tuán)的材料或者小分子。NHS在PH7-8.5與伯胺基團(tuán)反應(yīng)形成穩(wěn)定的酰胺鍵。 PEG化的活性酯具有很好的水溶性,在使用過程中要現(xiàn)配現(xiàn)用,將包裝從冰箱取出,置于干燥器當(dāng)中緩慢升至室溫穩(wěn)定,再打開瓶蓋,取用。取用后充入惰性氣體,封口膜封口,擰緊瓶蓋裝入自封袋,及時(shí)放入冰箱。
Active ester PEG (mpeg-nhs) is a peg derivative that can react with amino (- NH2) and can be used to modify proteins, polypeptides and any other materials or small molecules with amino groups. NHS reacts with primary amine groups at pH 7-8.5 to form stable amide bonds. The PEGylated active ester has good water solubility. It should be ready for use during use. Take the package out of the refrigerator, put it in the dryer, slowly rise to room temperature for stability, and then open the bottle cap for use. Fill in inert gas after use, seal with sealing film, tighten the bottle cap, put it into the self sealing bag, and put it into the refrigerator in time.
