Abstract
The present disclosure relates to methods of increasing the extraction of an apoplast-targeted recombinant protein in a plant tissue and to methods of increasing the purity of an apoplast-targeted recombinant protein recovered from a plant tissue. The methods involve contacting plant tissue with a rinse fluid on a plurality of occasions to release recombinant protein from the apoplast into the rinse fluid to create an apoplast wash fluid. The resulting content of the recombinant protein in the apoplast wash fluid is higher than the content of the recombinant protein in the apoplast wash fluid from comparable plant tissue contacted with rinse fluid on a single occasion.
