I'm not sure how the IgG concentration can be specifically measured with a spectrophotometer if there were other proteins in the vial. All proteins (containing aromatic residues) will absorb at 280nm. The only method I'm aware of for measuring IgG concentration in a solution with other proteins (such as serum or tissue culture supernatant) would be by ELISAagainst an IgG standard curve. I've discussed this with my colleagues, and we're wondering if the user has a reference for this method, or could he/she describe the protocol?

The antibody has been protein G purified and no proteins are added, so we expect it to be quite pure andintend to provide100 ug of IgG per vial. I see that the 3 new vials were delivered today, so if theend user does wish to test these vials then please keep me updated of the results. If the measurements are also coming up short or if the user prefers not to test them in light of the QC information, please let me know and we can arrange a credit or refund.

I apologize again for all of the inconvenience, and if there is anything else that we can do for you please let me know.

Thank you again for all of your patience regarding this issue.

I've heard back from the lab, and each new lot of antibody is tested after production (i.e. before lyophilization) using a Bradford assay and then is tested again after lyophilizaiton.

Please keep me updated once the new vials are received,and let me know if there is anything else that we can do for you. Have a great day.

Thanks again for all of your patience regarding this issue. I've set up the replacement order, and these vials will arrive on the order *** sometime next week. I will let you know as soon as I have more information from the lab about the QC process for the new lot.

Please let me know if there is anything else that we can do for you in the meantime. Have a nice day!

Thank you for your call today and for letting us know about the trouble with ab14498.

I apologize that I wasn't clear about when I would get back to you. I'll be working with the lab to determine the cause of this problem and fix it, but I'm also sending a vial from a new lot on the order *** which will arrive tomorrow. Please keep me updated about the mass in this vial, and if it is correct then I will send out two more vials from the same lot.

I look forward to hearing from you. Thank you for your patience, and I am sorry for this inconvenience. If there is anything else that we can do for you please let me know. Have a nice day.
