Thank you for your response and for clarifying the cell types used in the experiments.    I understand now that bEnd3 cells (immortalized mouse brain endothelial cell line) were stained for CD31. The protocol looks absolutely fine and it you have an alternative antibody which worked fine with these cells. I would like to reassure you that our Abpromise applies to your complaint since you purchased this product within the guarantee period. This means that in the event that a product is not functioning in the applications/species cited on the product data sheet (and the problem has been reported within 6 months of purchase) we will happily offer a credit note/refund to the value of the product purchased.   I could raise either a credit note for the cost of  one vial of ab7388 and ab7388 since you have alternative antibodies; or send you two replacement vials (one of each)  free of charge. Please could you let me know how you wish to proceed with your enquiry? I look forward to hearing from you soon.

Thank you for your response. Though you have kindly provided some details, it would be much appreciated if I could get some more information which would help me identify the source of the problem. 1)  Sample: Could you specify the samples used for the staining i.e. species, cells (cultured) or tissues? 2) Detection system: Have you used the secondary antibody successfully with another primary antibody? Do you think that the problem may come from the secondary antibody? Thank you for your understanding and co-operation in this matter. I look forward to hearing from you and hope to solve this problem as soon as possible.
