Which immunological technique is used to separate proteins based on their size?

Step 1: Understand that proteins are molecules made up of amino acids and can vary in size.
Step 2: Learn that scientists often need to separate these proteins to study them.
Step 3: Know that one common method to separate proteins is called Western blotting.
Step 4: In Western blotting, proteins are first placed in a gel and an electric current is applied.
Step 5: The electric current causes the proteins to move through the gel, with smaller proteins moving faster than larger ones.
Step 6: After separation, the proteins are transferred to a membrane.
Step 7: Specific antibodies are then used to detect the proteins of interest on the membrane.
