Flourescein labeling- Help!

  Our lab uses a large amount of fluorescein-labeled primers, and we are 
attempting to synthesize them ourselves instead of remaining at the mercy of 
suppliers for pure, high-quality primers.  We have no problem making the 
primers themselves, but we are having problems with labeling.

  Does anyone know how to label the 3' or 5' ends of double-stranded DNA?  (Or 
both?)  Does anyone have experience with flourescein-labeling primers?  200-bp 
ds DNA?

  Please send any primary references if possible, or advice if you don't have
