What is polyacrylamide gel electrophoresis?
Polyacrylamide gel electrophoresis (PAGE) is a method used to separate proteins based on their size and charge.
How does protein migration occur in PAGE?
Proteins migrate through the gel matrix in response to an electric field, with their movement influenced by their size and charge.
What are the applications of PAGE?
PAGE is commonly used in protein analysis, including purity assessment, molecular weight determination, and protein characterization.
What factors affect protein migration in PAGE?
The migration rate of proteins is affected by their size, charge, and the pore size of the gel matrix.
Is PAGE suitable for all types of proteins?
PAGE is suitable for a wide range of proteins, but the choice of gel concentration may vary depending on the protein size.
