I think almost all proteins in E.coli have their own pI between 4-10.
But there will an exceptions.
I have 2D PAGE graph between 4-8.
I want to know the protein distribution curve of E. coli cell extract.
(pI versus density(regardless of kinds)).
What proportion of proteins of E.coli cell extracts will be exist above pI 8

Thank you.
