	Cycling Probe Reaction (CPR) is an isothermal amplification 
for the detection of the presence of a particular DNA sequnence.  This
method utilizes the thermostable RNAaseH activity to cleave labeled
RNA molecule from the RNA:DNA hybrid.  Following RNA cleavage, the 
DNA molecule will bind fresh RNA molecule which is again cleaved.  
So the cycle continues.  The sensitivity of the method is very very
