The molecular mass of a protein is 50000 Da. (A) What is the mg/mL concentration of a 40-µM solution of the protein? (B) What is the percentage concentration of this solution?
You calculate via spectrophotometry that the concentration of a solution of a protein with a molecular weight of 22,680 g/mol is 75 µM. What is the concentration in mg/ml?
You are given a protein solution with a concentration of 0.15 mg/ml. v. Suppose that we want to prepare 100 microliters of 10 micrograms/microliters solution. How much of H2O and protein stock do we need to add to obtain the target concentration and volume? (THE CONCENTRATION IS NOT GREATER IN THE QUESTION, YOU NEED TO CONVERT IT TO MICROGRAMS/MICROLITERS.... THEN IT SHOULD MAKE SENSE) ****IF YOU ARE GOING TO WRITE THIS ANSWER OUT WITH PEN AND PAPER PLEASE WRITE IN...
If the molecular weight of Protein G:B1 is 8 kDa, what is the concentration (in mg / mL) of a solution of this protein which has an absorbance (A) =0.2 at l = 280 nm? How many grams of protein are present in 1 mL of this solution?
You are given a protein solution with a concentration of 0.15 mg/ml. We need 0.1 µg for an experiment. What volume of the protein solution do we need?
ncetoi paper) 1. BSA stock solution A has a concentration of 3.50 mg/mL. 1.00 mL of stock solution A is diluted to a final volume of 5.00 mL to prepare solution B. 1.00 mL of solution B is diluted to a final volume of 5.00 mL to prepare solution C. 1.00 mL of solution C is diluted to a final volume of 10.00 mL to prepare solution D. Calculate the concentrations of solutions E, C, and D. Show your work....

You have a protein solution. You take 5 ml of the solution, and add 25 ml of buffer. You then add 50 µl of the dilute protein solution to 50 µl of buffer and 2 ml of Coomassie solution. The resulting absorbance at 595 nm was 0.457. At the same time, you prepared a standard curve for the same protein using the same Coomassie assay protocol (100 µl of sample + 2 ml of coomassie reagent) The linear fit to...
Lab 5: Additional Dilution Problems You have a stock solution that contains 24 mg/ml of protein. You want to make a set of standards with the following concentrations: 12 mg/ml, 6 mg/ml, 3 mg/ml and 1.5 mg/ml You need a minimum of 500 ul of each standard after all dilutions are completed. Using the technique of serial dilution, explain how you would make your standards by filling in the chart below. Std 4 Std 1 12 Std 2 6 Std...
4. (a) Determine the experimental concentration of protein in the unknown solution in mg/mL using the Part II Data Table and the equation on page 2 for the absorbance assay at 280 nm. Hint: Convert the molar concentration (M or moles/liter) of BSA from absorbance assay at 280 nm method to mg/mL, assume that the molecular weight of BSA = 66.5 kDa [7 points 6500 g/mol Post-lab 10 Report Form: Determination the Concentration of a Protein You must show your...
