Blocking Peptide

Application / Dilution
ELISA50 ng/well

Size 50 μg



The Transient Receptor Potential Melastatin (TRPM) subfamily of cation-permeable channels is ubiquitous in mammalian tissues. This family includes TRPM1-8. In addition to acting as a calcium-permeant channel, some TRPM family members, TRPM6 and TRPM7, possess serine/threonine kinase activity and autophosphorylation. TRPM8 is thermoactivated at mildly cold temperatures (>25oC), and can also be activated by compounds that cause a cooling sensation, such as menthol and icilin. TRPM8 is expressed in trigeminal and dorsal root ganglia neurons where it confers sensitivity to cold in the somatosensory system. In vascular smooth muscle, TRPM8 may alter blood flow by constricting or enlarging blood vessels. TRPM8 is also expressed in normal prostate epithelial cells, as well as overexpressed in several primary tumors including colon, lung, skin, breast, and prostate cancers.

Western blot image of human TRPM8 in human MDA-MB-231 cells. The blot was probed with rabbit polyclonal anti-TRPM8 (extracellular region) without peptide blocking (lane 1) or with peptide blocking (lane 2).

TRPM8 synthetic peptide corresponding to amino acids in the extracellular region of human TRPM8. This site is well conserved in rat and mouse TRPM8, but has low homology to other TRPM family members.

The peptide is specifically recognized by TRPM8 (Extracellular region), antibody (TP5701) in ELISA, and has been shown to block the reactivity of TP5701 in Western blot. In addition, the peptide is recommended for use in blocking TP5701 reactivity in immunocytochemistry.

*All molecular weights (MW) are confirmed by comparison to Bio-Rad Rainbow Markers and to western blot mobilities of known proteins with similar MW.
