Dear Sir/Madam,
I have ordered this antibody and it worked very good in the first trial, but after that it did not works again.
I kept in at 4c so it not freezed.
I really appreciate if you can provide me with the reason of that.

Your inquiry has been forwarded to the supplier. According to the supplier datasheet, the product should be stored at 4 C, and it should last for one year. The most likely reason is the contamination and protein degradation, due to several reasons: bacteria growth, temperature change, prolonged storage. I wonder whether the free-thaw cycle in a regular frost-free fridge may encourage bacterial growth or not. Please see Labome article "Antibody Shelf Life/How to Store Antibodies
