9) In size exclusion chromatography, * smaller proteins are eluted faster than larger molecules cross-linking of polymer which comprises the stationary phase determines the pore size the most positively charge proteins are eluted last large proteins migrate the slowest through the column 10) In isoelectric focusing, * charge on the protein does not change as the protein migrates through the gel a protein has a net positive charge when it reaches a pH equal to its pI proteins can be separated based on their pI a thermal gradient is created in the presence of an electric field

Size-exclusion column chromatography and SDS-PAGE are methods used to separate mixtures of proteins. Match each statement with the appropriate category: Size-exclusion chromatography SDS-PAGE Both Answer Bank Proteins are separated by size. Proteins move toward the positive electrode. Smaller proteins travel faster during separation. Proteins are separated in their native state. Proteins of similar molecular weight but different shape can be separated. Proteins are separated in their denatured state. Larger proteins travel faster during separation.

Question 1: List two (2) major differences between ion exchange chromatography versus Size Exclusion chromatography. Use no more than 20 words for each difference. Question 2: In Gel filtration chromatography, larger molecules move faster in the polymer gel; but in electrophoresis SDS PAGE; smaller molecules move faster. Question 3: Someone wants to get rid of the excessive salt in a protein solution. What technique would be best for this purpose? (1 point) Question 4: A photo shown below is the result of a protein separation experiment. What technique has been used for this separation? (1 point) Isoelectric focusing.
