    摘要: Coupling of biological materials is disclosed via 4-hydroxy-3-nitrobenzene sulfonic acid sodium salt (HNSA) esters. The novel activated esters are structured so as to react at one end with an amine group of a selected biological or non-biological material, thereby releasing the spectroscopically monitorable HNSA dianion, and at the other end with, typically, a sulfhydryl group of a second material which may or may not be biological. The esters provide for a cross-linking reaction that may be easily controlled and monitored.

    摘要: Heterobifunctional crosslinkers up to about 34 .ANG. in length consisting of a sulfhydryl reactive group linked to a spacer group, which in turn is linked to an activated carboxylate group, that are useful for making efficacious anticancer immunotoxin conjugates as shown preferably by reacting an antibody associated amino group with the activated carboxylate group to form an antibody crosslinker complex and reacting the antibody crosslinker complex with a cytotoxin having a reactive sulfhydryl group with the sulfhydryl reactive group of the crosslinker, and using the conjugates so produced to treat cancer patients.
