ANSWER:

Thank you for your telephone call. I am sorry to hear you have had difficulty obtaining satisfactory results from this antibody.

I would like to reassure you that ab12269 Amyloid beta precursor protein antibody is tested and covered by our 6 month guarantee forWB 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.

As discussed on the phone, I would like to investigate this particular case further for you, and also obtain more information for our quality monitoring records.
