Study on noncovalent binding between ketoprofen and plasma protein by electrospray ion trap mass spectrometry 酮洛芬与血浆蛋白非共价结合的电喷雾质谱研究
Purer acetylcholinesterase was obtained through salting out by ammonium sulphate and ion exchanging 分别采用鸡蛋膜固定化法,活化载体共价结合法和戊二醛交联法进行酶的固定。
Considering when most of different atoms combine together , the covalent bond and the electrovalent bond are concomitant 考虑到大多数异类原子结合是采取共价结合与离子结合之间的过渡形式。
Covalent binding of antibody is particularly beneficial if a detergent has to be used as the blocking agent of the residual surfaces 如果去污剂作为残留表面的封闭剂,那么抗体的共价结合就特别有用。
The results shows that the concentration of acetylcholinesterase in earthworms was low , it was not steady and its loss during purification process was great 且纯化过程中损失较大,结果欠佳;活化载体共价结合法固定得到的乙酰胆碱酯酶酶膜活性高,酶不易损失,重现性好。
