Final answer:
Once an electrophoretic gel has been removed from its container, the proteins may be analyzed by all techniques EXCEPT: The correct answer is E: slicing the gel into fractions and isolating the proteins.
Step-by-step explanation:
The correct answer is E: slicing the gel into fractions and isolating the proteins. Once an electrophoretic gel has been removed from its container, proteins can be analyzed using various techniques, including:
- Their interaction with specific antibodies in a blot (immunoblot assay)
- Staining the proteins
- Attaching radioactive labels that can indicate positions on the gel by producing an autoradiograph
- Determining the net charge on each protein
However, slicing the gel into fractions and isolating the proteins is not a valid technique for protein analysis. This process is not commonly used in protein analysis and does not provide the ability to analyze the proteins in detail. The correct answer is E: slicing the gel into fractions and isolating the proteins.
