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

Ming, On that note, here is a Blue Native PAGE protocol that reportedly improves the separation of basic proteins. A friend and I have used it for native protein separation, but not necessarily for basic proteins. Word of warning: don't use histidine salts or Tris-HCl in the cathode buffer.

You could try Coomassie Blue Native gel. It's a very neat technique and it worked for me on a couple of occasions. In one unfortunate case, it resulted in dissociation of a heterotetrameric complex, though. Artem > Dear CCP4 community, > > Sorry for the off-topic subject, but I would really appre

Dear CCP4 community, Sorry for the off-topic subject, but I would really appreciate some suggestions and/or protocols relating to native gel electrophoresis of basic proteins. I have used a general acidic PAGE protocol for my protein, which has a PI of 9.5. Briefly, the protein was loaded onto a n
