The invention relates to novel conjugating reagents capable of reaction with at least one nucleophile present in a peptide or protein, which contain at least one leaving group which is lost on reaction with said nucleophile, in which the leaving group includes a portion —(CH2CH2O)n—, in which n is a number of six or more; and novel processes for the preparation of conjugates containing peptides or proteins made using such reagents.
本发明涉及能够与肽或蛋白质中存在的至少一个亲核物反应的新型共轭试剂,该试剂含有至少一个在与所述亲核物反应时失去的离去基团,其中离去基团包括-(CH2CH2O)n-部分,其中n为6或6以上的数字;以及使用此类试剂制备含有肽或蛋白质的共轭物的新型工艺。
