Dear xxxx
Thank you for your kindness!

The purchase number is xxxxx. Please let me know when I can have the new protein. I will also let you know the result of my assay.

Have a good weekend

Thank you for confirming that.

I have arranged for ab80369 to be sent to you. Unfortunately it is currently not in stock and is likely to take until the 10th of May to reach you. I am sorry for any inconvenience this caused you.

Thank you for your quick reply!

I am disappointed about what you said. You understood exactly what I need and the purchase was based on the information you provided. I don’t know why you decided not to refund this?

Regards

I am sorry that you are disappointed. I understood from our initial phone call that you had already purchased ab48801 and I therefore did not make the recommendation of ab80369 as an alternative immediately. As I said in my initial email to you, we hav...

Dear xxxx,

I bought the batch you below. However, I could not see any activity. Please see the file attached.

Is there any chance I can get the refund or you can give me some active Hsp90 instead?

Best wishes

I am sorry to hear that you found the protein Hsp90 alpha(ab48801) not to be active in your assay. As I mentioned in my previous email, as we have not performed any activity assays ourselves, we could not therefore be sure that the protein would be act...

Hi, Before ordering ab48801 I would like to know if you have verified either ATPase or functional activity of your Hsp90 protein stock? Regards

Thank you for contacting us. The source of the protein informed me that, regrettably, they haven’t tested the activity of the Hsp 90 (ab48801). There are no test scheduled for this particular protein in the near future because it requires radioactiv...
