A student is trying to add 9.0 pmol of primer mix to a 20.0 µL PCR. The primer mix is at a concentration of 50.0 µM, and the student determines that a serial dilution is required because directly adding the primer mix would require a volume less than 1.00 µL. The student takes 1.40 µL of the primer mix stock and mixes it with 25.0 µL of ultrapure H2O. Calculate the volume (in µL) of the intermediate solution required to add the correct amount of primer mix to the PCR.
The final amount of each primer required in a PCR reaction is 25 picomol. If the total volume of the PCR reaction is equal to 100 µl and the stock concentration of each primer is equal to 0.0025 mM. Calculate the volume of stock primer that needs to be added in order to ensure a primer amount of 25 picomol.
The tables below show the components for a single PCR reaction. To save time and effort, it is advisable to prepare a Master Mix for several reactions. If you were asked to prepare the master mix for N=50 reactions, how much of each component will you add?
