Abstract
This invention relates to a method for purifying and concentrating biologically active growth hormone to produce growth hormone in a form suitable for incorporation into a controlled release device (or system). A buffered solution of purified recombinant growth hormone is dialyzed against a buffered solution until the salt level is reduced to less than 5% and then lyophilized.
