So far in class I have learned c1v1=c2v2....it is said v1 is usually unknown. I am unsure how to solve this problem.

1.You have 23 uL of plasmid DNA that you want to run on a gel, but you only have 7X tracking dye. How much 7X tracking dye would you add to your sample before loading it on the gel?

Answer #1

7X loading dye means 1 part of dye and 6 part of sample is required to be loaded in gel i.e. 1microlitre will be dye and 6 microlitre would be the sample

c1v1 formula is required for dilution if 23 microlitre is sample then we use it as

1/6*23 = 4 microlitre of dye will be used

can also be calculated from unitary method
