Thank you for sending your protocol. I am sorry to see that this antibody and the LMX1a antibody ab31006 are both giving negative IHC results.

I think your protocol is good and I would expect to see a positive result for ab66941, though we have had mixed reports, as you can see from the customer reviews shown on the datasheet. There is a question of specificity according to one of the reviewers but the western blot data suggests the antibody is specific. For both reviewers, however, at least some staining was evident..

Can you please confirm that the species of your sample is mouse? Are you confident that the secondary antibody will recognize rabbit IgG, and that it is effective with other antibodies?

The LMX1a antibody was found some years ago to be ineffective for IHC. We unfortunately do not have another antibody against this protein that has been shown to be capable of staining tissue sections.

Can you please tell me approximately when you placed your order for the LXM1b antibody? I am willing to discuss replacing it,, as IHC of mouse tissue is covered by our guarantee, though our choices of good alternatives is very limited.

Thank you for sending the questionnaire.

It is difficult to guess, the identity of band at 30kDa which is consistent in all lysates. The only lysate which shows correct band size is LMX1B trans-fected Hek 293 cells. In regards to other lysates I am sorry we are unable to determine the identity of extra bands; you may need further optimization of the application. My suggestions for optimization would be

- Include negative control i.e. lysates without primary antibody
- Prepare lystes with 80-90% cell confluency
- Keep the lysis buffer at 4C when lysing the cells
- Boil the lysates in sample buffer for 10 minutes at 100C.

Please note that the purchase of this antibody is out of Abpromise guarantee. However we are happy to help as far as we can.

I hope these suggestions will help to improve results. If these doesn't please let me know, I will then try to replace the antibody free of charge.

Thank you for contacting us.

I am sorry to hear you are experiencing difficulties with one of our products. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

I am attaching our questionnaire so that we can gather further information regarding the samples tested and the protocol used. Once we receive the completed questionnaire, we will look at the protocol and see if there are any suggestions we can make that may improve the results. This information will also allow us to investigate this case internally and initiate additional testing where necessary. If the product was purchased in the last six months and is being used according to our Abpromise, we would be happy to replace or refund the antibody.

I look forward to receiving your reply.

PS: We are not sure which other company is showing this image however this antibody and other 3, ab70174, ab82835 and ab129306 are fully guaranteed for detection of LMX1B with human lysates.

We unfortunately have image for this antibody only.
