Need help figuring out the calculations for the stock solution please. Required Reagents 50 mM Tris pH 7.5 buffer Sephadex G-75 or G-100 Sample Protein Mixture (2 mg/ml. blue dextran, 4 mg/ml. mystery protein, 0.4 mg/mL DNP. aspsartate) ONPG Note:. You will need at least 400.0 mL so, the 50 mM Tris pH 7.5 buffer that you will make from a 1.0 M stock buffer solution. You will not need to check the pH after diluting the stock solution.
