Anti-COX2 / Cyclooxygenase 2抗体[5E10/D10] (ab701)

Thank you for your enquiry. We are very sorry for the trouble and for not choosing the right antibody. Please do not despair! The antibody may work in your system; it has just not been characterized for cross-reaction with rat. But it does not necessarily mean that it does not recognize rat COX2. We would therefore suggest a couple of things: 1. Try to use a well-established positive control (from human or mouse, these two species have been tested) and run your samples along with it to be able to identify the bands. 2. As you probably know, COX2 (Cyclooxygenase 2) is an inducible enzyme. COX2 expression markedly increased in 85-90% of human colorectal adenocarcinoma. A single band at around 72kDa is expected, however we have received a report from a customer working with this antibody that they obtain two strong bands in WB - one between 40 - 50kDa and other between 62 - 83kDa. Are the two bands you have around these sizes? Please do let us know how you are getting on with this antibody. Your results are interesting and we would be very grateful for you if you can submit a review about this antibody once you are confident with the results. We can update our on-line datasheet with your findings and in return we can we will send you an Amazon voucher. Good luck with your experiments!

We currently don't have an integrin beta 1 antibody that has been tested for application in both ELISA and Western blotting. I have contacted our accounting department and instructed them to issue you a refund for ab701. If I can be of further assistance, please do let me know.

Thank you very much for the details that you have provided and for your patience. I have contacted the originator of this antibody and am waiting to hear if there have been any other complaints regarding the lot that you have received. As we have had no other complaints concerning ab701, my feeling is that there very well may be a problem with the lot/vial that you received. We do have a newer batch in stock and I can send it to you as a free of charge replacement. Alternatively, I can offer you a refund or a different antibody to try. Please let me know which you would prefer, and once again I thank you for your patience.

There has been no further information for the antibody's cross reactivity with rat. We do not have another mouse COX 2 in our range.
