vinny, I am guessing the disadvantage to using goats and mammary glands is that the genes are much more difficult to manipulate and more time consuming to arrive at a new protein expression.

But it is ironic that you are now arguing that transgenic goats are a more natural way of expressing glycoproteins Vs genetically altered yeast.

In addition to all the other proteins that get expressed at the same time and the concern about prions.

With these genetically engineered yeast and filamentous fungi it seemed important to me that you can get a pure product and you have a platform where you can quickly change the characteristics of the glycoproteins expressed.
