Solution II

From 2011.igem.org

0.2 N NaOH    [Think M when you see N]
1.0% SDS

The ideal Solution II would be freshly made, using 10 N NaOH.

To make 5 ml of Solution II using 0.4 N NaOH stock and 10% SDS stock solution we use:

 2.50 ml 0.4 N NaOH
 0.05 ml 10% SDS
 2.45 ml distilled water or NF water
