Biotinylated Primer for S1 probe?

[phillip buckhaults]

Would someone post advice on S1 nuclease protection to map transcriptional start 
sites?  I would like to make use of a biotinylated primer i have to synthesize a 
probe, either by using klenow or PCR, and then blot the protected products for 
avidin-AP detection.  I have no experience with this kind of assay, so there may be 
an obvious reason why using a biotinylated primer will not work.  Any comments on 
this type of approach, or a pointer to a good traditional protocol would be helpful.  

thanks in advance.
