1. Robin is planning to use AKTA system chromatography with SP HiTrap column. She will use a line...
#2 is Q HiTrap column where it is anion exchange column not
cation
2. Predict the order that the following proteins will elute from a CM Sephadex column run at pH 6.5 using a NaCI gradient: fibrinogen (pl-5.8), hemogloblin (pl7.1), ribonuclease A (pl7.8), lysozyme (pl-11), pepsin (pl-1.0) 3. In the laboratory we ran an immunoblot on fractions obtained from the alkaline phosphatase experiment. This procedure requires a number of steps, two different antibodies and a detection method. You should be...
ANSWER ALL 1) Which of the following is the stationary phase in size exclusion chromatography? A. resin B. mixture of proteins C. solvent or buffer D. none of these 2) Suppose you wish to purify a protein that has many positively charged residues from a mixture of proteins. Which of the following columns would elute the protein the fastest? A. column packed with neutral resin B. column packed with positively charged resin C. column packed with negatively charged resin D....
1. A protein retained on an affinity chromatography column is usually eluted off the column by: none of these applying low pressure to the column gradually increasing the salt concentration of the elution buffer. adding excess of the protein's ligand. changing the pH of the elution buffer. 2. In two-dimensional SDS-PAGE protein analysis, proteins in a mixture are separated by their: affinity for polyacrylamide and overall hydrophobicity PI and molecular weight molecular weight and overall hydrophobicity overall hydrophobicity and PI...
please show work for both with labels and explainations
this is an example of what is expected
Draw the elution profile for a size exclusion column with an exclusion range of 50 kD to 500KD on which are separated. Make sure you indicate the bed and void volumes Myoglobin Hemoglobin Immunoglobulin Glutamine synthetase 17 kD -68 kD 150-200 kD 400 kD Draw the elution profile for an S sepahrose, cation exchange column pl 10.3 on which MW Cytochrome C Ribonuclease...
