Method for producing and identifying soluble protein domains

摘要

Methods for producing and identifying fragments of proteins, and more particularly to methods for generating and identifying soluble protein domains are disclosed based on a method for generating a library of nucleic acid fragments from nucleic acid encoding a desired polypeptide, and more especially a library of essentially, randomly sampled fragments of coding DNA sequence predominantly of defined size range and a method for selecting cloned gene fragments from the library that encode soluble protein domains.
