Abstract
This invention discloses a commercially advantageous process for extraction and purification of protein from microorganisms. The initial steps of the process are useful for purifying many insoluble proteins while later steps are designed to renature denatured somatotropins produced by transformed microorganisms. The process is especially useful for purifying recombinantly-produced bovine somatotropin.
