Question (24871) | Anti-CD13 antibody [EPR4058] (ab108310)

Go to datasheet (ab108310)


Hello, We have recently received a consignment of antibodies from you on Friday. Unfortunately, I was not informed of this delivery until today and therefore the antibodies have been left at room temperature over the weekend. I have now placed the antibodies immediately into 4C for storage but am wondering if these antibodies would still be viable after being left at room temperature all this time. These antibodies are unconjugated antibodies (both monoclonal and polyclonal). I would appreciate if you can let me know as soon as possible. Many thanks. Regards,


Thank you for contacting us. Abcam takes product quality seriously and we recently undertook an in-depth study examining storage conditions and antibody performance. After over 13,000 individual ELISA experiments, we have determined that storing our antibodies at various temperatures of up to 45°C for 1 week does not impact their activity. I would be happy to share a summary of our findings with you; please let me know if you would like to see this. As a precautionary measure only, we ship our antibodies in packaging with ice packs to provide extra temperature stability in transit. The ice pack may be thawed or even at room temperature when you receive it; please be assured that this is normal and that your product is safe to use. Once you have received the vial, please follow the long-term storage instructions on the datasheet. Our Abpromise to you is that, should our product not work as stated on the datasheet, we will resolve the issue to your satisfaction, either with helpful advice to optimize your experiment or a replacement or refund of the product. Please contact our knowledgeable Scientific Support staff should you experience any issues while using our products. Contact information can be found at: I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information. PS: Attached is the tested data of few of our antibodies.
