Never heard of. Could you tell what the heck this EMPHAZE is? 
Very curious. Is there any reason you want to use this instead of  
well-documented sepharose and likes?
Then what is to be linked to it? Oligos or big DNAs (ss or ds)?
What is the method of coupling? What typical capacity for 
proteins does 3M specify?
