A Cost-effective Method for Expression and Purification of Recombinant Proteins in Plants
- Summary
- Downstream purification of recombinant proteins from plant-based samples is performed by Elastin-like polypeptides (ELP)-intein fusion expression and purification through temperature-sensitive inverse phase transition of ELP and cleavage reaction of intein.

Title: COST-EFFECTIVE METHOD FOR EXPRESSION AND PURIFICATION OF RECOMBINANT PROTEINS IN PLANTS
Usefulness: COST-EFFECTIVE METHOD FOR EXPRESSION AND PURIFICATION OF RECOMBINANT PROTEINS IN PLANTS
Summary: For obtaining desired protein from plants, plant parts, or plant cells; where desired protein is lectin or cytokine; and for producing fusion protein having elastin-like polypeptide (ELP)-intein tag (claimed). Also useful for producing recombinant proteins such as pharmaceuticals, antibody chains, industrial enzymes, and other useful proteins.
Novelty: Obtaining protein from plants involves forming protein extract from plant having fusion protein having at terminal(s) elastin-like polypeptide and splicing intein tag, aggregating, resolubilizing, cleaving and separating protein from tag(s)
