Thank you for contacting us.

The lab sent me more information about the immunogen of the antibody ab62256:

The antibody is against both EPHA2 and EPHA3. This antibody recognizes EPHA2 when it is phosphorylated at Y588 and EPHA3 when it is phosphorylated at Y596. Also, alignment of our immunogen sequence with the provided sea urchin sequence shows an 88.9% identity.

Thank you for contacting us.

The immunogen for the anti-phosphorylated Eph receptor antibody, ab62256, is identical to the sequence you provided, at least around Y588. I have asked the laboratory to provide a more precise alignment (I do not have access to the exact immunogen sequence).

Regarding samples, we do not have any for any of our products. Given that sea urchin is an untested species, reactivity is not covered by our guarantee. However, we do have a testing program which will provide a credit for the cost of the antibody if you first provide us with your data, regardless of whether it is positive or negative. Can you please tell me what assay you anticipate using, for example, western blotting or immunocytochemistry, or other? You will need a discount code before purchase of the antibody, which I will be happy to provide.

Thank you for contacting us. I am sorry to hear that this antibody did not work as expected. I can certainly arrange a refund for you, but would like to gather some more information about the actual problem for our records. Please let me know: 1) What application were you using and what was the exact problem encountered (e.g. no bands/staining, high background etc) 2) What samples did you use (type of tissue/cells) and how were they prepared? 3) What is the antibody dilution and incubation time employed? 4) What was the blocking reagent? 5) What secondary antibody and detection system was used? Is it working well with other primary antibodies? 6) What controls (positive and negative) did you use? Thank you so much! I also wanted to point out that besides the option of refund, other options would be a free of charge replacement (with another antibody or an antibody to a different protein) or a credit. I look forward to hear back from you and assist you further.
