Anti-serum albumin domain antibodies for extending the half-lives of short lived drugs

Abstract excerpt

We have used phage display to isolate a range of human domain antibodies (dAbs) that bind to mouse, rat and/or human serum albumin (SA) and can be expressed at very high levels in bacterial, yeast or mammalian cell culture. In contrast to non-SA-binding dAbs, which have terminal half-lives of less than 45 min, the half-lives of these 12 kDa 'AlbudAbs' can match the half-life of SA itself. To demonstrate the use...
