Question (22737) | Anti-SUR1 antibody (ab32844)

Go to datasheet (ab32844)


Thank you for your email. I was away for conference in July and later busy with timelines after the conference. My lab staffs (a Research Associate and a technician) have been doing further testing of the three antibodies we purchased earlier. 1) Anti-TRPM7 (AB85016) antibody: still not able to confirm any 220kDa band of WB in native neuronal cells and HEK cells. 2) TRPM2 antibody (AB11168) is not good as well - still with too many bands on WB using brain tissue. 3) anti-SUR1 antibody (AB32844): using very high concentration (1:100) on WB and long incubation time (3 days), we could see a weak band around 175 kDa. Wondering if the concentration is correct in the lot / shipment? If possible, we would like to have: 1) refund on item #1 (AB85016) and item #2 (AB11168), 2) replacement for anti-SUR1 antibody (AB32844) to try one more time in WB. Thank you very much for your consideration.


Thank you for contacting us. I am sorry to hear you are experiencing difficulties with one of our products. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly. I am attaching our questionnaire so that we can gather further information regarding the samples tested and the protocol used. Once we receive the completed questionnaire, we will look at the protocol and see if there are any suggestions we can make that may improve the results. This information will also allow us to investigate this case internally and initiate additional testing where necessary. If the product was purchased in the last six months and is being used according to our Abpromise, we would be happy to replace or refund the antibody. I look forward to receiving your reply. PS: Please include images for each antibody also. Images always helps in understanding the problem quickly.
