A scientist wants to separate a mixture of two proteins. Protein A has a pl of 3.2 and protein B has a pl of 10.5 making them ideal candidates for separation by ion exchange chromatography. The scientist chooses to run the experiment at neutral pH using a positively charged resin. Which of the following statements about this experiment are true? i. Protein A will elute out of the column before protein B. ii. Both of the proteins, A and B, will bind to the resin. iii. A higher concentration of salt solution would be needed to elute protein A from the column than to elute protein B. iv. We would expect to see equally good separation if the scientist had chosen to use a pH of 2

Typed and correct answer please

A scientist wants to separate a mixture
of two proteins. Protein A has a pl of
3.2 and protein B has a pl of 10.5
making them ideal candidates for
separation by ion exchange
chromatography. The scientist chooses
to run the experiment at neutral pH
using a positively charged resin. Which
of the following statements about this
experiment are true?
i. Protein A will elute out of the column
before protein B.
ii. Both of the proteins, A and B, will
bind to the resin.
iii. A higher concentration of salt
solution would be needed to elute
protein A from the column than to
elute protein B.
iv. We would expect to see equally
good separation if the scientist had
chosen to use a pH of 2
