ABSTRACT:
The present invention provides a method for producing a free flowing and/or non clumping resin that includes prior to drying, shrinking the resin under agitation. In one variant of the invention, the is a resin used in solid phase synthesis of peptides. In another aspect the invention provides a process of making a peptide using the free flowing resin described herein, and a polypeptide made using the process. Various therapeutics are then be made using the polypepdite.
