Abstract [en]

Protein fusion tags are important tools in research when robust methods for protein purification and detection are required. In this chapter we present an efficient method for stringent protein purification. A small domain, denoted ABDz1, with affinity for both human serum albumin and Protein A has been developed. The purification tag is based on an albumin-binding domain from Streptococcal Protein G that was engineered to bind Protein A. The ABDz1-tag can be fused to any protein of choice and the purification can be performed using standard laboratory equipment. In this chapter a method for purification of ABDz1-tagged proteins using two successive affinity purification steps is described.
