Abstract: Abstract: Human serum albumin fusion technique is a popular technology in extending half life of protein and polypeptide drugs. The fusion technique has recently become an effective tool in biological pharmacy. The distinct activity between fusion proteins of various fusion patterns, how to improve the yields of fusion proteins and the degradation question of fusion proteins are three key points of human serum albumin fusion technique. In this review, we briefly summarize the fusion pattern, high expression and degradation of fusion proteins in drug half-life extension, to provide some technical references for the wide application of human serum albumin fusion technology in the future.
