Abstract: Novel, substantially isolated isoforms of human platelet-endothelial cell adhesion molecule-1's, DNAs coding for transcripts that encode the novel isoforms and others, including a previously identified soluble isoform, methods of using such DNAs to make isoforms by expressing the DNA's, and promoter segments controlling transcription of human platelet-endothelial cell adhesion molecule-1 genes are provided. The novel isoforms differ from the complete human platelet-endothelial cell adhesion molecule-1's in lacking one or more segments near the C-terminus encoded by exons 10-15 of the genes for the full length molecules and arise in vivo from alternative splicing of the transcript from the genes.

Abstract: Immunophilin ligands act by binding to receptor proteins, immunophilins, which in turn can bind to and regulate the Ca.sup.2+ dependent phosphatase, calcineurin, and the Ca.sup.2+ release channel, the ryanodine receptor. Immunophilin ligands have been discovered to enhance neurite outgrowth in neuronal cell systems by increasing sensitivity to neurotrophic factors. The effects of the immunophilin ligands are detected at subnanomolar concentrations indicating therapeutic application in diseases involving neural degeneration.

Abstract: A method for purifying and recovering biologically active somatotropin monomers from refold solution following the solubilization and naturation of refractile bodies of host cells produced by recombinant DNA methodology. The purification process is based on the discovery that somatotropin monomers and somatotropin oligomers having overlapping isoelectric points may nevertheless be separated by selective precipitation over a narrow pH range. Host cell residues including proteins, pyrogens and other impurities present in the refold solution are effectively removed in the process. The purified somatotropin monomers recovered from solution after removing precipitated solids are suitable for parenteral application to target animals without further purification.
