10X Annexin V Binding Buffer (ab14084)

Thanks for information. I do not have time to look with whom I should
contact, but I recently ordered ab14084 Annexin-V binding buffer and it
does not work at all, whereas the equal buffers from BD Sciences and
Beckman Coulter worked fine. Your FITC labelled Annexoin V is fine.
Any suggestions?
Best,

 We just received this complaint from the customer below:  I ordered Oct, 12 (order 3-4901676515) 2x 50ml Abcam Annexin V 10x Binding Buffer ab14084. I received 2 bottles coming from 2 different lots. Doing my assays end last week the Annexin staining didn’t work. I investigated the 2 lots and saw that lot #GR59518-1 which was used doesn’t work whereas lot#GR48964-2 works perfectly. I have 20ml left from #GR59518-1. What shall I do, sending it back for an exchange and to where? It’s really annoying when a big sophisticated experiment is failing do to a faulty buffer.  Thank you for your quick reply in how you handling this matter! Yours kindly

ANSWER:

Thank you for contacting Abcam Technical Team and for taking the time to provide some useful details of the experiments. I am very sorry to hear that your customer is having problems with this product.

Although the batches are different, both bottles are from the same internal lot number. I regret to inform you that this means that there should be no difference between the two bottles. Just to clarify, the internal lot number is an identification number for the synthesis/purification/manufacturing process. The product can be placed to our different stocks in different times and the batch numbers (GR48964-2 and GR59518-1) represent when the actual aliquots were placed into our stock.

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 can certainly offer a new free of charge replacement bottle if your customer would like to get one.

Please do let me know how your customer would like to proceed. I look forward to hearing from you soon.
