Hi netters,

Does anyone know if biotin-dNTPs (i.e., biotin-dCTP, biotin-dATP; linker 
omitted) incorporate at a significantly different efficiency than 
biotin-14-dUTP during PCR??

We used to use biotin-14-dUTP, but due to a problem with licensing, our 
vendor switched to biotin-14-dCTP and following the same protocols with 
everything else apparently the same, we don't feel we're getting the same 
level of incorporation.  Does anyone know of, or observed, such differences
in incorporation, especially as Boehrringer Manheim has doubled the price
of their biotin-14-dUTP in the last year because of the noted problems 
with licensing (they wouldn't lie to me, would they?).

Regards, Peter
