        Subcloning Tips - very important heating step

         
        Source: Schimmelpenninck
        Abstract: Put your insert and vector in an Eppendorff tube and then heat it for 5 minutes, then add ligation buffer and ligase

        After isolating your digested fragments from the gel put digested vector and digested insert TOGETHER in an Eppendorff tube, then put this for about 5 minutes at 65 degrees celsius, then cool it and spin it down, then add your ligation buffer and ligase. The 65 degrees celsius step is VERY important.

        Short explanation:
        your insert is EcoRI/SalI
        and vector is EcoRI/SalI
        The heating step will break all the UNWANTED AND TOTALLY USELESS insert-insert and vector-vector bindings. After the heating step MANY good vector insert bindings will occur and your plates will be full of good transformants.
