Chemiluminescent HRP Substrate (membrane) (ab5801)

Thank you for your enquiry. I can confirm that both products (ab5801 and ab65623) can be used for Western blot application, however ab65623 can be applied for more test (50). Your customer may be interested in our very new range of WB reagents (Optiblot) and further information can found at this site: www.abcam.com/optiblot I am happy to arrange a discount if they would like to try this product. I hope this helps and if I can assist further, please do not hesitate to contact me.

Thank you for calling Abcam. I have not been able to find a chemiluminescent EMSA kit in our catalogue. We do have several protein extraction kits though, please see the list below: Mammalian Cell Extraction Kit  ab65399 Plasma Membrane Protein Extraction Kit, ab65400 Please let me know if there is anything else I can help you with.

Thank you for contacting us. We have two anti-M13 antibodies that may be of interest: ab6188 Anti-M13 + Fd Bacteriophage Coat Proteins antibody Binds specifically to phage coat proteins of M13 or fd phage. Click here (or use the following: https://www.abcam.com/M13--Fd-Bacteriophage-Coat-Proteins-antibody-ab6188.html). ab50370 Anti-M13 antibody [B62-FE2] (HRP) Binds to an epitope on pVIII (phage coat protein) covering the N-Terminal region of the g8p AEGDDPAKAAFDSLQASAT. Click here (or use the following: https://www.abcam.com/HRP-M13-antibody-B62-FE2-ab50370.html). We have a number of HRP kits, mainly for IHC. Here is a link to a HRP substrate than can be used for WB: ab5801 Chemiluminescent HRP Substrate (membrane) Click here (or use the following: https://www.abcam.com/Chemiluminescent-HRP-Substrate-membrane-ab5801.html). Please let me know if there is anything else I can help you with.

I can confirm that the chemiluminescent peroxidase substrate ab5801 is actually a bit more sensitive than the ECL or ECL+ products. The fact you are having low signal with this substrate and the antibodies ab6721 and ab12856 could be due to a number of reasons, either protocol related or antibody/reagent related. The kit should be stable for a minimum of 18 months at 2-8 degrees C, if it is older than that it may have gone off. I would be happy to look at your protocol to see if the problem can be solved with protocol tips, if you can click on the link below this will take you to a short protocol questionnaire to put the information together. https://www.abcam.com/index.html?section=western&pageconfig=technical&intAbID=12856&mode=questionaire The antibody ab12856 has been tested in WB by a customer who left a review of their results, this was done on transfected cells and therefore maybe basal levels in your samples are very low? Do you have reports of your samples expressing GPCR MRGX1? We look forward to receiving your protocol to help you more,
