2132321 9319091 PCTABS00025 A tripartite fusion protein comprises a first amino acid sequence corresponding to a glutathione-S-transferase enzyme at its COOH terminus with a second amino acid sequence corresponding to a binding entity, particularly an immunological binding entity, followed by a third amino acide sequence corresponding to a different polypeptide fused with said binding entity. The protein may include a cleavable link between the first and second amino acid sequences and/or the second and third amino acid sequences. Recombinant DNA molecules and expression vectors coding for these fusion proteins are also disclosed.
