The invention provides for a method of crosslinking a hetero-bifunctional photo crosslinking compound to an immunoglobulin having at least one heterocyclic photo reactive group and at least one non-photo reactive group where the non-photo reactive group is coupled to an effector molecule and the photo reactive group is coupled to the nucleotide binding site of an immunoglobulin. Alternatively, the photo crosslinker contains an orthogonal reactive group such as a thiol, which can be coupled to an effector molecule or functionalized ligand.
本发明提供了一种交联异构双官能团光交联化合物到至少具有一个杂环光反应基团和至少一个非光反应基团的免疫球蛋白的方法,其中非光反应基团与效应分子耦合,而光反应基团与免疫球蛋白的核苷酸结合位点耦合。或者,光
交联剂包含一个正交反应基团,例如巯基,可以耦合到效应分子或功能化
