Question

A method requires 5 mM ATP (molecular weight 400). The reaction will be carried out in a 250 μL final volume. What volume of each of the stock solutions below (a – d) would you need to add to the reaction to give 5 mM ATP? Which of the stock solutions could NOT be used as a stock ATP solution for this reaction? a. 100 mM ATP; b. 2% (w/v) ATP; c. 100mg/dL; d. 10 mg/mL;
