You have a solution containing 10mg/ml of protein bovine serum albumin (BSA). MW of BSA is 68000. Calculate the concentration of this solution expressed as mM (Express your answer to two decimal places, don't forget the unit symbol, do not place a space between the numerical value and the unit symbol in your answer).

You are supplied with a 10mg/mL bovine serum albumin (BSA) stock solution made up in phosphate buffered saline (PBS). You need to make a 2mg/mL BSA standard solution from the BSA stock solution. How much 10mg/mL BSA stock solution and how much phosphate buffered saline (PBS) do you need to make 10mL of a 2mg/mL BSA working standard.

One gram of serum albumin in 1 dm3 of water gives a solution height of 3.9 mm when separated from pure water by a semi permeable membrane at 25°C. The molar mass of serum albumin is(density of solution 1.0 g cm-3; g = 9.81 ms-2)

Problem PageQuestion114.mg of an unknown protein are dissolved in enough solvent to make 5.00mL of solution. The osmotic pressure of this solution is measured to be 0.0355atm at 25.0°C.Calculate the molar mass of the protein. Round your answer to 3 significant digits.

A 20 mL protein fraction recovered from a column chromatography was analyzed for protein usingthe BCA method. The following data were the means of a duplicate analysis using BSA as astandard:2The average absorbance of a 1 mL sample was 0.44. Calculate protein concentration (mg/mL) andtotal protein quantity of this column fraction. (Hint: use Excel to establish the calibration curve)
