Asked on Nov 22 2011
Thank you for your phone call. I am sorry to hear that these 3 antibodies are not providing satisfactory results. The details provided will enable us to investigate this case and will provide us with vital information for monitoring product quality. As we discussed over the phone, I would like to offer some suggestions to help optimize the results: For ab413, ab415 I'd suggest using less primary and/or secondary antibody as the membrane shouldn't turn black. This might be an indication of too much antibody on the membrane. For ab109451, most likely using less primary antibody could help with the background as the recommended dilution for the antibody is 1/10,000 to 1/50,000. Should the suggestions not improve the results, please do let me know. In the event that a product is not functioning in the species and applications cited on the product datasheet (and the problem has been reported within 6 months of purchase), we would be pleased to provide a free of charge replacement, credit note, or refund. I hope this information is helpful, and I thank you for your cooperation.
