- Given a stock protein solution with a concentration of 3 mg/ml, determine the protein concentration of a solution made by mixing 5 μl of the stock with 5 μl of a buffer.Using DEAE-cellulose as ion exchange resin, indicate the starting and ending pH for the narrowest experimental pH range used to separate an amino acid mixture consisting of Gln, Leu and Lys Starting pH: _____ Ending pH: _____True or False Immobilization improves the stability of the enzyme. EnaLne, has a half-life of 10 days in free solution, but under identical conditions of temperature, pH, and medium composition, the measured half-life of a packed column is 30 days. The enzyme is immobilized in a porous sphere 5 mm in diameter.
- A mixture of lipids containing phosphatidic acid, cholesterol, testosterone, phosphatidylserine, andphosphatidylethanolamine was applied to a hydrophobic interaction chromatography column. Thecolumn was washed with a high salt buffer, and the lipids were then eluted with decreasing saltconcentrations. In what order would the lipids be eluted from the column? Explain your answer.Calculate the concentration of 0.2ml amino acid when path length is 1cm and has an absorbance value of 0.50, if a 0.5ml solution of same amino acid has a concentration of 0.72mg/ml with an absorbance of 0.9.Titration curve of an unknown amino acid The graph below shows a curve, which was obtained following titration of an unknown amino acid. Include a suitable descriptive title stating the identity of the unknown amino acid Use rectangles to precisely outline the regions in the graph where ionisable groups show buffering activity (base/acid ratio 1:10 to base/acid ratio 10:1); clearly associate the name of the ionisable group with the buffering regions; indicate within the graph all observable titration mid-points and all observable titration end-points and indicate estimates of the pKa of the three functional groups (do not provide pka values from the literature, you need to read the pka from the titration curve provided). Note that it is not possible to estimate the pka with more than one decimal precision due to limited resolution of the shown graph.
