- An ion exchange chromatography is used to purify proteins whose net charge is zero when the solution ph is 8 what would be the protein containing solution have to be?
Answer: 7
Explanation: At a pH below their isoelectric point (pI) or net charge, proteins carry a net positive charge and conversely, At a pH above their pI they carry a net negative charge. as per the question protein carry a net negative charge. So the protein containing solution have to be 7 to become it neutral.

SIRJE GEL OBJECTIVE: Partial purification of a protein, isocitrate dehydrogenase (IDH), using DEAE ion exchange chromatography. IDH will be eluted from the column using increasing concentrations of KCI. IDH will be tracked using the IDH activity assay and the extent of purification will be analyzed using SDS PAGE Last week we assayed for the activity of the enzyme, isocitrate dehydrogenase, from E.coli strains carrying a plasmid that over-expresses the E. coli IDH gene. To purify proteins from cel extracts, biochemists...
