Two improved procedures were developed for activating ferritin so that the ferritin could be covalently linked to antibodies. One procedure involved use of a water-soluble carbodiimide and N-hydroxysuccinimide to prepare ferritin-containing activated esters. The other involved activation of the ferritin with excess glutaraldehyde. The ferritin-antibody conjugates prepared with the two procedures were shown to have a number of properties which made them suitable for locating antigenic components in cells.
开发了两种改进的方法来激活铁蛋白,以便铁蛋白能够与抗体共价连接。一种方法是使用水溶性碳二亚胺和N-羟基琥珀酰亚胺来制备含铁蛋白的活化酯。另一种方法是用过量的戊二醛激活铁蛋白。用这两种方法制备的铁蛋白-抗体缀合物显示出许多特性,使其适合于定位细胞中的抗原成分。
