Hi Ming, You can find a protocol for low pH native gel electrophoresis (as well for high pH and blue native) in the following book: Gel Electrophoresis of Proteins: A Practical Approach (Practical Approach Series) by B. D. Hames. http://www.amazon.com/Gel-Electrophoresis-Proteins-Practical-A

There is a 20-inch (20-3D2W04) display that costs around $6000. For $13000 you get a 42-inch, so I guess the 52-inch that was introduced today will cost a lot. Vangelis On Jun 5, 2008, at 7:30 PM, Juergen Bosch wrote: Interesting! Their PDF says it works with OpenGL: http://www.busin

2008-03-05 Thread Vangelis Christodoulou
Hi Evette, Have you tried to mutate one glycosylation site at the time and check for expression? Often glycosylation is necessary for secretion -that's the case with my protein. Also these sites tend to have a defined glycosylation pattern which eliminates the need of deglycosylation. You c
