V2 is the final volume of the diluted solution. An example of a dilution calculation using the Tocris dilution calculator What volume of a given 10 mM stock solution is required to make 20ml of a 50 M solution Using the equation C 1 V 1 C 2 V 2 , where C 1 10 mM, C 2 50 M, V 2 20 ml and V 1 is the unknown. 8 microgramsml (gml), and that the standard was initially diluted 1100 with six subsequent twofold serial dilutions. Based on the amplification efficiency, we can know which method can be used to calculate the expression level. Serial dilutions can be calculated either using a starting concentration and dilution factor OR a concentration range. . erotic massages near me
