    • Function

      Receptor-activated non-selective cation channel involved in detection of sensations such as coolness, by being activated by cold temperature below 25 degrees Celsius. Activated by icilin, eucalyptol, menthol, cold and modulation of intracellular pH. Involved in menthol sensation. Permeable for monovalent cations sodium, potassium, and cesium and divalent cation calcium. Temperature sensing is tightly linked to voltage-dependent gating. Activated upon depolarization, changes in temperature resulting in graded shifts of its voltage-dependent activation curves. The chemical agonists menthol functions as a gating modifier, shifting activation curves towards physiological membrane potentials. Temperature sensitivity arises from a tenfold difference in the activation energies associated with voltage-dependent opening and closing.
    • Tissue specificity

      Expressed in prostate. Also expressed in most in prostate tumors. Also expressed in non-prostatic primary tumors such as colon, lung, breast and skin tumors.
    • Sequence similarities

    Thank you for contacting us.

    Yes, we recommend running the WB in reduced and denatured conditions.

    You can find the recommended protocol here:

    Thank you for contacting Abcam.

    We spoke earlier about two antibodies:
    anti-BMPR2 ab78422 (
    anti-TRPM8 ab109308 (

    You mentioned you were interested in testing ab78422 in mouse via IHC-P prior to using the antibody in human samples. Since this would be a mouse on mouse stain, there will be a high level of background due to the mouse antibody binding to native IgG's present in the mouse tissue. Also, our AbTrial program does not apply to mouse on mouse applications. Thus, I highly recommend testing the antibody in your human sections, perhaps sections that are not as crucial to your experiment.

    Additionally, purchase of ab78422 would entitle you to a free rabbit monoclonal antibody through our RabMab promotion. Details of this promotion are given below:
    Free Rabbit monoclonal antibody with any purchase of a primary antibody, while stocks last! Quote “RABMAB-XBSMG” in your next primary antibody order. For more information, visit the following link:

    Thus, you would be able to receive ab109308, the anti-TRPM8 RabMab that we looked at together earlier with the purchase of ab78422.

    We also have anti-mouse and anti-rabbit secondary antibodies that could be used for ab78422 and ab109308, respectively.

    We also discussed some IHC-P protocol information. I've attached our protocol book which includes IHC-P protocol information as well as other applications. Specifically for ab78422, we discussed attempting a proteinase K enzymatic antigen retrieval. Information regarding a proteinase K antigen retrieval is given below. I also recommend primary antibody dilutions of 1/50, 1/100, and 1/200 to see which dilution gives the best signal to background ratio.
    Proteinase K antigen retrieval information:

    We also discussed the western blot bands that you were seeing for TRPM8, with 2 bands appearing (1 at the expected 130 kDa and 1 at 60 kDa). Since the TRPM8 protein is a homotetramer, the 60 kDa band is most likely a homodimer composed of half of the TRPM8 protein. In order to reduce the likelihood of this lower weight band occurring, you can also attempt denaturation in SDS at 70oC for 5-10 minutes rather than boiling at 95-100oC.

    I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

    Thank you for your interest in these antibodies. Without a discount the prices range from €360.00 to €370.00. A bulk order discount of approximately 5% is available for orders of 5 units or more of 5 different antibodies. The discount my colleague mentioned in an earlier e-mail is not a discount per se, but an offer of a free antibody in exchange for data from testing of an antibody that has been purchased already. Further, the offer is only available if the data is from a previously untested species or application (which are not covered by our guarantee). For example: Antibody ab74846 has been tested on human samples in several applications: IHC on frozen tissue (IHC-Fr), IHC on paraffin-embedded tissue (IHC-P) and western blotting (WB). Click here (or use the following: If your samples are other than human (e.g., mouse, rat, etc.) or if the application you want to use the antibody for is other than IHC or WB (e.g., immunoprecipitation or ELISA, etc.), our guarantee of a replacement or a credit/refund if the antibody fails does not apply. However, if you send us your data, whether positive or negative, and you have a "discount" code, then the code will be active when we receive your data, and you can use it to receive another antibody for free when you place an order, for instance any of the other TRPM8 antibodies. I will need to know how you intend to use the antibody before I issue the discount code (or codes, if you want to test more than one antibody). I hope this makes sense. Please let me know if you have any questions. I look forward to your reply.
