Black hole quenchers (BHQ) and 3' blocking in Real-time PCR

[chovek69]

Dear experts,

I am relatively new in the Real-time PCR world.  I am about to order a
bunch of hydrolysis probes quenched with the BHQ.

The company states exclusively that they can do 3' - BHQ labeling but
is this also mean that the 3'-OH will be blocked by the quencher
against extension  or I must order 3' phosphorylation in addition.

Any suggestions will be most welcome...
Thanks
Ivan
