摘要 |
The present invention discloses methods used to estimate the in vivo half-life of a binding protein of interest. The disclosed methods involve (a) determining for a binding protein of interest and for each of at least two different reference binding proteins an in vitro half-life using an in vitro protease reaction assay, wherein said reference binding proteins have known different in vivo half-lives, (b) determining the correlation between the known in vivo half-lives and the in vitro proteolytic half-lives of each of the reference binding proteins, and (c) estimating from said correlation between the known in vivo half-lives and the in vitro proteolytic half-lives of the reference binding proteins the in vivo half-life of the binding protein of interest that correlates with the in vitro proteolytic half-life of the binding protein of interest. |
