Customer reviews and Q&As


Thank you for contacting us and your interest in our products.
The antibody you are interested in, the anti-Connexin 37 / GJA4 antibody (ab16587), has been raised against an immunogen taken from the rat protein. This immunogen shares 100% homology with the mouse protein and the antibody would therefore be expected to be able to detect the mouse protein. However, as we have not tried it ourselves I would not be able to guarantee this.
We are unfortunately unable to offer free samples of any of our products. This is due to the logistics that this would involve. We do however have a testing discount scheme which may interest you.
This offer means that if you purchase ab16587 as usual, test the antibody with your mouse protein and let us know of the results through an Abreview (no matter whether positive or negative) you would be eligible for a free primary antibody of your choice from our catalogue. More information on this offer can be found here: www.abcam.com/collaborationdiscount
The only constraint of this offer is that the antibody to be tested needs to be purchased, tested and the free antibody claimed within 4 months. 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 ab16587.
I hope this information has been of help. If you require any further information please do not hesitate to contact us again.
