Rabbit Anti-Goat IgG H&L (Biotin) preadsorbed (ab7131)

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

Reviewing the details, I agree there seems to be some crossreactivity to mouse IgG. I can confirm that this antibody has not specifically been pre absorbedwith mouse, so we cannot guarantee it would not crossreact with mouse. However, I appreciate the time you have spent on these experiments and would be pleased to arrange afree of charge replacementor credit note in compensation.

If you decide on a free of charge replacement, I can suggest it would be beneficial to select an alternativeantibody that has been cross absorbed with mouse, so there is minimal possible crossreactivity. For example you may like to consider the following which has been tested and guaranteed in ELISA:

ab7124 Donkey anti-Goat IgG H&L (Biotin) secondary antibody

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

Thank you for your telephone call yesterday afternoon. I am sorry to hear you have had difficulty obtaining satisfactory results from this antibody and have some concerns about crossreactivity to mouse..

I would like to reassure you that this antibody is tested and covered by our 6 month guarantee. 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.

As discussed on the telephone, I would like to investigate this particular case further for you, 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.

I would appreciate if you could also provide any data which would help us to assess the results.

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