Abstract

Virtually all methods for reading the sequence of bases in DNA rely on the ability to denature double-stranded DNA into single strands and then use Watson-Crick base-pairing rules to hybridize the strands with high specificity to another DNA primer or probe. However, nature frequently uses an alternative method, reading the sequence information directly from double-stranded DNA using sequence-specific DNA-binding proteins. Here we describe methods for the construction and testing of sequence probes based on engineered zinc finger DNA-binding proteins. Background is reduced using split-reporter molecules, and signal is amplified using enzymatic reporters. The resulting sequence-enabled reassembly (SEER) probes can be configured to detect DNA sequence (genetic) or DNA methylation (epigenetic) information.
