  • Antibodies to a testis-specific differentiation-regulatory factor
    Patent number: 7288635
    Abstract: A gene expressed specifically in the testis has been unexpectedly isolated in the course of studies of the expression of a gene encoding an unknown protein that triggers cell death. The isolated gene was a novel gene sequence that had no significant homologue in the database. This gene was also found to be involved in the regulation of differentiation in the testis and to encode a protein, Tesmin, which may regulate the differentiation of spermatogeneous cells into primary spermatocytes. Tesmin proteins are described herein, as are antibodies that bind to such proteins.

  • Vasoconstrictor peptide
    Patent number: 4981950
    Abstract: Disclosed is a vasoconstrictor peptide called Endothelin having a molecular weight of 2,500.+-.300. Endothelin contains 21 amino acid residues, wherein four cysteines form two sets of S--S bond.In order to obtain the vasoconstrictor factors of the present invention, it is preferable to culture the endothelial cells collected from the vascular inner walls in a serum-free medium.The vasoconstrictor peptides of the present invention can be utilized as hypotension therapeutic agents or local vasoconstrictors to animals including humans.
