Thank you for your patience.

I have heard back from the lab and for ab72454, the homology with mouse is, unfortunately,not greater than 50%. Thus, the chance of crossreactivity is quite low and I would not recommend trying this antibody in mouse.

However, ab57827 shows a 100% homology of the immunogen with mouse and might be worthwhile trying. I can offer you a testing discount code for trying this antibody in mouse, besides sending it to you free of charge.

Other options to resolve this case are either a credit or refund.

Please let me now how you would like to proceed.

For UNTESTED species and/or applications, we have established a testing discount program. Here is a brief description of how it works:
The testing discount program is for customers who like to use an antibody/protein/kit on an untested species/application. You would purchase the antibody/protein/kit at full price, test it and submit an Abreview with your data (positive or negative). On your next order you will receive a discount for ONE antibody/protein at the full price (100%) of the antibody/protein you have tested, or a full price discount for the amount paid for the kit. The terms and conditions applicable to this offer can be found here: https://www.abcam.com/collaborationdiscount.
This programapplies to ELISA kits and other kits we offer.

I lok forward to hear back from you.

Thank you for your reply. The information is very detailed and it is disappointing that the optimization steps did not help improve the results. The additional testing seems to confirm that the product received is not working as expected. The customer may of received a faulty vial therefore I would be happy to replace or refund the product. Please could you confirm the customers preference. Looking forward to your reply.
