Melanocortin (MC) 3-MSH (Melanocyte-Stimulating Hormone) is believed to signal through the MC 3 receptor. It induces a sustained increase in intracellular free calcium levels ([Ca2+]i) in a subpopulation of pituitary cells. Most of the cells responding to 3-MSH express more than one pituitary hormone mRNA. The effect of 3-MSH is blocked by SHU9119, a MC3R and MC4R antagonist, in only 50% of the responsive cells, suggesting that in half of these cells the mediating receptor is not the MC3R. Low picomolar doses of 3-MSH increase [Ca2+]i in the growth hormone (GH)- and prolactin (PRL)-secreting GH3 cell line.

BIS-TRIS propane (BTP), a novel multidentate ligand of nickel- and cobalt-based spin clusters, is a metal chelator. BIS-TRIS propane is often used as a zwitterionic buffer for PCR and protein crystallization studies.

Gp100 (25-33), human TFA is a 25-33 amino acid fragment of human melanoma antigen.Gp100 (25-33), human TFA is a 9-amino acid (AA) epitopes restricted by h-2db and recognized by T cells.
