Dear Ishita:

  I always use CTAB to remove polysaccharides from my DNA 
preparations.  If any polysaccharides still remain after CTAB
purification, you can use PEG precipitation to get purer DNA.

  If you do not know how to use CTAB and PEG to purify DNA, you
are welcome to check my home page and find them at:

good luck!
