I had tried 5 times used the ab4469 antibody and It did not work. And I had tried 5 times, so I bought another antibody UPSTATE:17-663, and had got the anticipate result. The condition were as follows: The concentration of the primary antibody was 1：1000; The concentration of the secondary antibody was 1：5000; So I thought there was something wrong with this antibody and did not want to try again.

Thank you for contacting us. I am sorry that the results did not improve. I would like to ask how you would like to proceed with this case. In order to help you further I would need more information about order number. The order number you have provided does not match actual Abcam order. It looks like you are from China and you may have purchased this antibody from our Chinese distributor. Please contact them for contacting us for further instructions. Please be advised that I can only provide free of charge replacement or refund/ credit note if the antibody was ordered within Abcam guarantee period; which is 4 month for Chinese customers. If you are not from China please accept my apologies for misunderstanding and provide me the correct 6 digit Abcam order number. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
