1. A method for analyzing a target nucleic acid, the method comprising the steps of:
- forming droplets containing a single target nucleic acid and one or more amplification reagents;
amplifying the target in the droplets;
distinguishing droplets containing amplicon from the target and amplicon from a variant of the target generated by polymerase error by using two differently labeled-hybridization probes, one hybridizing to the target and one hybridizing to a specific variant of the target; and
analyzing target amplicons.

Abstract
The invention generally relates to droplet based digital PCR and methods for analyzing a target nucleic acid using the same. In certain embodiments, methods of the invention involve forming sample droplets containing, on average, a single target nucleic acid, amplifying the target in the droplets, excluding droplets containing amplicon from the target and amplicon from a variant of the target, and analyzing target amplicons.
