    摘要: Methods for producing polypeptide with altered immunogenicity or improved stability properties are disclosed. The methods involve a) expressing a diversified population of nucleotide sequences encoding a polypeptide of interest, b) screening the polypeptides expressed in step a) for function, immunogenicity and/or stability, c) selecting functional polypeptides having altered immunogenicity and/or increased stability, e.g. functional in vivo half-life as compared to the polypeptide of interest, and d) optionally subjecting the nucleotide sequence encoding the polypeptide selected in step c) to one or more repeated cycles of steps a)-c). In a further step the expressed polypeptides of step a) or c) can be conjugated to at least one non-polypeptide moiety.

    摘要: The invention provides variant lipases with improved washing performance, including good performance in washing with a detergent having a high content of anionic surfactant at low washing temperature at a short washing time. More particularly, the invention relates to variants of the wild-type lipase from Pseudomonas sp. strain SD 705, deposited as FERM BP-4772.
