The standard protocol uses Lysis Buffer PL1, which is based on the established CTAB
procedure. Additionally, the SDS based Lysis Buffer PL2 is provided which requires
subsequent protein precipitation by potassium acetate (Precipitation Buffer PL3).
For some plant species Lysis Buffers PL1 and PL2 can be used with similar results.
However, for most plant material the lysis efficiency is different due to the negative
charge of SDS and the positive charge of CTAB.
