It won't bind to just any sequence, however it may be that if the 20mer 
has the right secondary structure from it's sequence you may well be 
able to get a specific sequence that would bind streptavidin.

In general you will need a biotin group on the oligo.


The problem with being on the cutting edge is that you occasionally get
sliced from time to time....
