    Can I prepare 100ng/ml solution from 10ug/l stock solution?
    Thanks...

    No. 10g/L is also 10 ng/ml. Your stock is weaker than what you wish to prepare. You need to concentrate it, not dilute it.

      Thanks JohnS, I figure it out yesterday, I used another stock solution.

        Need to convert 1200 nM to ng/mL, the molecular weight is 595.8

          M is a symbol for molar, a concentration of moles per liter, so
          1200 nmol/L x 595.8 g/mol x 1L/1000 mL = 714.96 ng/mL
