Abstract
The present invention provides systems and methods for production of activatable diazo-derivatives for use in labeling nucleotides. Labeling nucleotides is accomplished by contacting a stable hydrazide derivative of a detectable moiety with an activating polymer reagent which is used to directly label the nucleotide sample. Labeling occurs on the phosphate backbone of the nucleotide which does not perturb hybridization of the labeled nucleotide with its anti-sense strand. Since the method involves direct labeling, all types of nucleotides can be labeled without prior amplification or alteration.
