Jesse it's correct that mannosylation at Asn257 can serve to enhance ADCC but assuming that is what Dr Meade was referring to you are mistaken that CHO cannot enjoy that type of engineering. cf http://www.freepatentsonline.com/y2007/0092521.html
>I did get the distinct impression from Dr. M. that the binding the NK cells is the most important action.
I don't doubt that at all. The citation mentions another case where the apportionment of ADCC enhancement between two alterations is controversial (fucose vs N-acetyl-glucosamine).
I am glad to be having this little chat because it reminds us that our glycosylation characteristics are fundamental positives, slide bullets in their own right, sometimes overshadowed in the investment narrative.
