Make 1nm, 500pM, and 100pM samples for each ratio

1:1

• 50nM: (500nM)V=(50nM)(50μL)

5μL 500nM solution in 45μL buffer

• 1nM: (50nM)V=(1nM)(50μL)

1μL 50nM solution in 49μL buffer

• 500pM (0.5nM): (1nM)V=(0.5nM)(50μL)

25μL 1nM solution in 25μL buffer

• 100pM (0.1nM): (0.5nM)V=(0.1nM)(50μL)

10μL 0.5nM solution in 40μL buffer 1:5, 1:10, 5:1, 10:1, and 50:1 calculations done in the same way
