Which of the Following Techniques is Used for Protein Isolation

Question

Which of the following techniques is used for protein isolation and purification?
A)ion exchange chromatography
B)Edman degradation
C)PCR
D)gas-liquid chromatography

Accepted Answer

Ion exchange chromatography is a technique commonly used for protein isolation and purification. It works by utilizing the charge properties of proteins to separate them based on their interactions with charged resin beads. Edman degradation is a method used for protein sequencing. PCR is a technique used for amplifying DNA, not protein isolation. Gas-liquid chromatography is a technique used for separating and analyzing volatile compounds, not proteins.
