DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. For other IHC staining systems automated and non-automated customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times. The gel was run at V for 50 minutes before being transferred onto a Nitrocellulose membrane at 30V for 70 minutes.
Antibody binding was detected using an anti-rabbit antibody conjugated to HRP, and visualised using ECL development solution. Click here to view the general protocols. Publishing research using ab?
Please let us know so that we can cite the reference in this datasheet. Can you please send me the amino acid sequence of the peptide used for immunization to make these antibodies? Thank you for contacting us. While the immunogen sequences for our antibodies are considered proprietary, we do provide general information about the immunogen range on our datasheets: ab Synthetic peptide based on the Human sequence. The antibody epitope is located in loop 3 of TIMP2.
The epitope is located in loop 1 of TIMP2. I hope this helps, please let me know if you need any additional information or assistance. Thank you for your offer. As for the IP, I am not sure me or my colleagues plan to do it in time for the expiry date of the offer you mention. But I won't totally rule it out either ; Anyhow, thank you very much for your help. Just one last question. Could you please let me know by when I should expect the delivery for the antibody?

It worked for the first couple of times, but after that, the antibody seems to have lost activity, since I cannot detect it anymore, on WBs or even on IHC. We have been regular users of Abcam products and never have we experienced any sort of troubles with your products.
They always worked perfectly well. But in this case, I just wanted to report this discrepancy to you, and ask if you could maybe replace the antibody with another vial but, probably from another batch or so. Also, this antibody is quite important for my project, and I would like to have it as soon as possible. If theres any queries, you may please get in touch with me at the numbers listed below.
Please do let me know what can be done. Hoping to hear from you soon! Thank you for your contact regarding ab I am very sorry to hear that you are having problem with this antibody. I understand from your e-mail this antibody has been used in Western blot and IHC application and it worked initially but failed to work later on.
According to our record, testing discount code was offered to you to test one vial ab in immunoprecipitation IP. Have you had a chance to use this product in IP? Would you be so kind to explain how the antibody was stored after arrival? I look forward to hearing from you and hope to solve this problem as soon as possible. Is the Western blot information in the datasheet for this antibody based on native or denaturing conditions?
