Purification of a transcription factor

Dear netters,

	Since I enjoy this section, here I come again with another 
question. I am currently working on the purification of a DNA-binding 
protein. I know exactly which sequence my protein binds. My intention is 
to purify it using columns coupled with mutated oligo (to remove all the 
non-specific interactions) followed by a column containing the WT oligo.

	Here is my questions: What is the best protocol or system to 
purify a DNA-binding protein using oligonucleotides coupled to a matrix ? 
Also, what is the best way to couple an oligonucleotide to a cellulose or 
other matrix ???

Thanks in advance
