High Speed Ultracentrifugation

High speed ultracentrifugation

A) allows separation of proteins of varied molecular weights, but only if the proteins in the mixture differ by >50,000 MW
B) allows separation of proteins of varied molecular weights, but only if the proteins in the mixture differ by >5,000 MW
C) allows separation of proteins of varied molecular weights, but only if the proteins in the mixture differ by >100,000 MW
D) does not allow separation of individual proteins
E) is commonly used to separate positively-charged proteins from negatively-charged proteins
