Recombinant Anti-ABCG5 antibody [EPR6203] (ab124965)

I now have more information to share with you in regards to the immunogen used to raise the anti-ABCG5 antibody ab124965. As can be seen from the attachment, the immunogen used to raise this antibody also does not share high homology with the rat protein (76%). However, it is higher than either of the two other antibodies, ab69713 or ab87116.
I would suggest the best option may be to try the antibody ab45279 as this has been raised against the full length protein. If you would like to try this I would be able to offer you a testing discount. This would involve you purchasing ab45279 as usual, testing it with your rat samples and sharing the results (regardless of whether positive or negative) through an Abreview. You would then be entitled to a free primary antibody of your choice (or the equivalent price of ab47279 off any product in our catalogue).

If you would be interested in participating in this scheme please do let me know as a discount code needs to be issued prior to the purchase of ab47279.
I hope this information has been of help. If you require any further information please do not hesitate to contact us again.

Thank you for contacting us and your interest in our products.
The ABCG5 antibodies which we have are all directed against the human protein. This shares 79% homology with the rat protein. We have not tested any of the anti-ABCG5 antibodies we have with rat samples, and we have had no reports of our customers having performed these experiments either. This does not mean that it would not work, simply that it has not been tested as yet.
In the attached pdf you can find the sequence alignment of the human protein and rat protein as well as the immunogen sequence used to raise the anti-ABCG5 antibodies ab69713 and ab87116. As can be seen from this sequence alignment, these antibodies are very unlikely to be able to detect the rat protein as the homology within the immunogen region is very poor. You may have more luck in using the rabbit polyclonal ab45279 although I cannot guarantee this. I am currently seeking further information as to what the immunogen sequence used to raise ab124965 has been to see if this is more likely to work in your experiments.
I hope this information has been of some help, I will let you know as soon as I have further information to share in regards to ab124965.
