Abstract
The invention is directed to a releasable conjugate comprising a biotinylated ligand having a biotin moiety, a ligand moiety (Ligand) and a biotin-binding molecule (bbm) bound to the biotin moiety of the biotinylated ligand. The ligand moiety of the biotinylated ligand may be separated by a spacer group consisting of polyethylene glycol. Furthermore, the invention relates to a method for cleaving the releasable conjugate by providing biotin or streptavidin and an auxiliary release agent in a sufficient concentration to displace the biotin-binding molecule (bbm) from the biotin moiety of the biotinylated ligand and a method for separation of target cells from a cell sample utilizing the conjugate.
