Purification of recombinant protein by cold-coacervation of fusion constructs incorporating resilin-inspired polypeptides.

Polypeptides containing between 4 and 32 repeats of a resilin-inspired sequence AQTPSSYGAP, derived from the mosquito Anopheles gambiae, have been used as tags on recombinant fusion proteins. These repeating polypeptides were inspired by the repeating structures that are found in resilins and sequence-related proteins from various insects. Unexpectedly, an… (More)
