ABSTRACT:
Biotinylated pharmacologically active agents and complexes containing same are disclosed. In particular, biotinylated-chemokines are described. The complexes further include an anti-biotin antibody that selectively binds to biotin. The complex can be dissociated by contact with free biotin. The complexes are particularly useful for enhancing an immune response to tumor cells and virus-infected cells, in vivo or in vitro.
