Anti-Insulin degrading enzyme / IDE 抗体 (ab32216)

Thank you for confirming these details and for your cooperation. The details provided enable us to closely monitor the quality of our products.

I am sorry this antibody did not perform as stated on the datasheet and for the inconvenience this has caused. As requested, I have issued an aternative free of charge replacement of ab133561 with the order number 1213991.

To check the status of the order please contact our Customer Service team and reference this number.

Please note that this free of charge replacement vial is also covered by our Abpromise guarantee. Should you still be experiencing difficulties, or if you have any further questions, please do not hesitate to let me know.

I wish you the best of luck with your research.

Thank you for your reply.

I would like to reassure you that we monitor feedback closely on a weekly basis and we are not currently concerned about the general quality of ab32216 IDE antibody or this batch. Regrettably, I can suggest you have received a bad vial on this occasion.

Therefore, we would be pleased to provide a replacement from the same antibody, which will still be covered by our guarantee. Alternatively, I fully understand your concerns and if you prefer an alternative replacement of ab133561 or a credit note in this case, I will be pleased to arrange this for you.

I can confirm that ab133561 IDE antibody is tested and guaranteed for both human samples and WB. All tested applications and species covered by the 6 month guarantee are listed on the individual datasheets. The replacement vial will also be covered by the guarantee.

I hope this will be helpful. I look forward to hearing from you with details of how you would like to proceed.

Thank you for your message and for providing this further information.

I apologize for the confusion, this is clearer to me now. I am sorry to hear the suggestions made have not improved the results on this occasion. Unfortunately, reviewing the details I am uncertain as to why this antibody is not working in WB for you when it is giving successful results in ICC.

I appreciate the time you have spent on these experiments and would be pleased to arrange a free of charge replacement or credit note in compensation.

I look forward to hearing from you with details of how you would like to proceed.

Thank you for taking the time to complete our questionnaire.

The details you have kindly provided will enable us to investigate this case for you and this is also helpful in our records for monitoring of quality.

Reviewing this case, I would like to offer some suggestions to help optimize the results. I would also appreciate if you can confirm some further details:

1. There are inherent difficulties with antibody detection of recombinant tagged proteins that I can recommend considering. This may be a biological artifact rather than a problem with the antibody. Could you confirm that the protein transfected is full length and includes the immunogen sequence? Also, if the recombinant IDE is tagged, it is possible that the tag is preventing access to the antibody. Could you confirm at which region of the protein the tag has been placed?

2. Could you confirm the species from which the recombinant IDE gene was taken?

3. Could you confirm how the stability of transfection has been assessed?

4. I can recommend that due to the points described above, it is important to use an endogenous positive control sample. For example, this antibody has been used successfully on mouse and rat brain lysate.

5. Has the transfer of protein to the membrane and quality of the sample been assessed using a loading control?

6. Was the same antibody used for detection of a signal in the ICC experiments?

I hope this information is helpful, thank you for your cooperation. Should the suggestions not improve the results, please do not hesitate to contact me again with the further requested details. I hope we can resolve this case for you as soon as possible.

Thank you for taking the time to contact us. I am sorry to hear you have had difficulty obtaining satisfactory results from this antibody.

I would like to reassure you that this antibody is tested and covered by our 6 month guarantee for WB and human samples. In the event that a product is not functioning in the tested applications and species cited on the product data sheet (and the problem has been reported within 6 months of purchase), we will be pleased to provide a credit note, free of charge replacement or refund.

I would be pleased to help troubleshoot, and also obtain more information for our quality monitoring records. In order to proceed with this, I have enclosed a technical questionnaire below. I would appreciate if you could complete this. It will help you put the information we require together very easily which will enable us to better understand the problem and provide assistance.

I would appreciate if you are also able to provide an image which would help us to assess the results.

Thank you for your time and cooperation. We look forward to receiving the completed questionaire.
