The present invention features a method for isolating and purifying proteins and peptides of interest from a plant host, which is applicable on a large scale. Moreover, the present invention provides a more efficient method for isolating proteins and peptides of interest than those methods described in the prior art. n In general, the present method of isolating proteins and peptides of interest comprises the steps of homogenizing a plant to produce a green juice, adjusting the pH of and heating the green juice, separating the target protein/peptide from other components of the green juice by one or more cycles of centrifugation and/or resuspension, and finally purifying proteins and peptides by such procedures as chromatography and/or salt precipitation. |
