H-Arg-4MβNA (H-Arg-4MbNA) is a peptide that serves as a substrate for cathepsin H. The enzyme activity is often detected in gel electrophoresis.

Gp100 (25-33), human is the amino acids 25-33 fragment of the human melanoma antigen. It is a 9-amino acid (AA) epitope restricted by H-2Db and recognized by the T cells.This is amino acids 25 to 33 fragment of human melanoma antigen gp100. This H-2Db restricted epitope is recognized by T cells. The gp100-specific, H-2Db-restricted, CD8+ T cells are capable of recognizing B16 melanoma but not normal melanocytes.

(D-Trp12,Tyr34)-pTH (7-34) amide (bovine) is a potent and competitive antagonist of parathyroid hormone (PTH), with a Ki of 69 nM in bovine renal cortical membrane. (D-Trp12,Tyr34)-pTH (7-34) amide (bovine) can be used for growth and development regulation.
