I hope this will be useful, but please let me know if you have any questions or if there is anything else that we can do for you, and I'll be happy to help.

Thank you for contacting us and reporting the problems encountered in using the anti-TGF beta Receptor II antibody (ab61213). We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

If you have been using the antibody with mouse, human or pig samples likely to express the TGF beta Receptor II then the antibody would indeed be covered by our Abpromise guarantee. I would therefore be happy to consider organising a replacement antibody, a credit note or refund for you. I will look into which otherTGF beta Receptor II antibodiesmay be appropriate foryou.

However, in order to understand the situation more fully I would really appreciate it if you could give me a few more details of what you have been observing. This information will also allow us to investigate this case internally and initiate any additional testing where necessary. To this end, I have attached a questionnaire in order to gather more information. If you could complete this and include some images of the results that would be very helpful.

I look forward to receiving your reply.

Thank you very much for this valuable feedback!

As requested, I have issued a credit not for you to use for the other antibody (see below).

Having done this, I would like to reassure you that we have strict quality controls for all our products in place and only antibodies that have passed all levels are sent out. Also, we monitor customer feedback closely on a weekly basis and we are not currently concerned about the general quality of TGF beta Receptor II antibody ab32798. The customer feedback you are referring to is related to a single issue that one of our many, many customers had with his particular samples (transfections are always a bit tricky). And as you may have noticed, the antibody vial used by this customer was obviously older than two years and we do not know if it was stored correctly over this long period of time. Thus, the problems observed could very well have been related to these issues. For this reason it is important that if you encounter any problems with our products, please report them within six months of purchase, to be fully covered by our guarantee: www.abcam.com/Abpromise.

But whom am I telling this?! You thankfully alerted us of the problem you observed in due course, and so I am pleased to send you the credit note details as requested:

Your credit note ID is x.

I am sorry that this antibody did not perform as stated on the datasheet, I have asked our Finance department to issue a credit note for you. The credit note may be used in one of the following ways:

(1) Redeemed against the original invoice if this hasn't already been paid.
(2) Held on the account for use against a future order.
(3) A full refund can be offered where no other invoices are outstanding.

To receive a refund or to confirm how you would like to use the credit note please ask your Finance department to contact our Finance department at creditcontrol@abcam.com or by telephone using the information at the “Contact Us” link in the top right corner of our website.

The credit note ID is for your reference only, please refer to the credit note ID in any correspondence with our accounting department. We will send you the completed credit note by email or postal mail with the actual credit note number which will start with the letters CGB.

I wish you the best of luck with your research, and hope this experience will not prevent you from purchasing other products from us in the future. Our Scientific Support team is always at your service should you require further expert advice.

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

The details you have kindly provided will provide us with vital information for our monitoring of product quality.

Reviewing the details, I am sorry to let you know that we do not have an explanation for the results you obtained. It might be that you have regrettably received a bad vial.

We sincerely apologise for the inconvenience, and I am pleased to offer you a free of charge replacement as requested. Unfortunately, we currently do not have ab61213 in stock. If you wish, I could send Anti-TGF beta Receptor II antibody ab32798 as replacement or any other primary antibody of your choice. Otherwise, I would be pleased to issue a credit note in compensation.

Thank you for your cooperation. I look forward to hearing from you with details of how you would like to proceed.

Kind regards and

Thank you for contacting us.

I am sorry to hear you have been experiencing problems with one of our antibodies. The quality of our products is important to us and I would like to reassure you that we investigate all customer complaints.

I appreciate the time you have spent in the laboratory and understand your concerns. It is regrettable the results have not been successful. Before deciding how to proceed, I would like to investigate this particular case further for you, and also obtain some further information for our quality records. Therefore, I would appreciate if you can confirm some details of the procedure:

1) At which dilution/concentration have you used ab61213?

2) How long was the exposure time?

3) Have you performed a no-primary control?

4) Have you run a loading control? If so, is the size of the band as expected?

It is indeed puzzling that you observe such nice bands below 55 kDa instead of 64 and 67 kDa, respectively. The above questions will help us to resolve the problem and send you a free of charge replacement.

As positive control we would recommend NIH-3T3 cell lysates. We have them available in our catalogue under ab7179; however, there should be no difference to the samples you loaded.

I look forward to your reply.

Thank you for contacting us.
