How to dilute from stock to get the right conc? - (Aug/09/2008 )

Hey any help will be great.

Basically at work I need to make a 5pmol/ul conc of an reageant from a 100pmol/ul stock. How do I go about to working out how much distilled water I need to add to make the 5pmol/ul conc?

If there is some kind of formula to work out for other conc like to make 25pmol/ul conc from a 100pmol/ul stock pls let me knw makes my like soo much easier.

Thanks in advance

As do I -- it's a very useful equality.

And don't forget that pmol/ul is NOT the same thing as picaMolar.
