reduce probe length

I can think of two ways, but you probably need to determine  
conditions empirically to get the size range you want. I would  
suggest you either increase the amount of template going into the  
reaction, or reduce the amount of dNTPs you're using in the reaction.  
Either way, dNTPs will be limiting which should lead to smaller  
labeled products.

Hope this helps.
