Free flow-isoelectric focusing of human cellular lysates as sample preparation for protein analysis.


A whole cell lysate of human cells was separated into 80 fractions according to the pI of proteins using free flow isoelectric focusing with carrier ampholytes. The resolution of the process was highly reproducible, with an overlap of fractions of less than 30%. A protein of a faint silver stained spot in two-dimensional gel electrophoresis (2-DE) could be… (More)
