Polony sequencing methods
First Claim
1. A method for obtaining the sequence of a polynucleotide comprising an unknown sequence, the method comprising:
- providing a polynucleotide library comprising a plurality of polynucleotide fragments comprising unknown polynucleotide sequences;
providing a substrate comprising a set of polynucleotide fragments having known nucleotide sequences from a reference genome;
sequencing the ends of the library of polynucleotide fragments, thereby creating partially-sequenced fragments;
comparing the sequenced ends of the partially-sequenced fragments to the reference genome;
sequencing the rest of the partially-sequenced fragments, wherein sequencing the partially-sequenced fragments comprises;
contacting at least a portion of the partially-sequenced fragments with the substrate under conditions suitable to allow the partially-sequenced fragments to hybridize with a complementary substrate polynucleotide fragment; and
detecting the hybridizations; and
obtaining the sequence of the entire partially-sequenced fragments from the known polynucleotide sequence of reference genome to which the partially-sequenced fragments hybridize.

Abstract
We describe ultra-high throughput polony genome sequencing that can permit, for example, generating raw data to re-sequencing the human genome in about one week (including library prep and sequencing) at a reasonable cost. The methods described herein include one or more of the following: (1) increasing polony sequencing read length, (2) improving library construction and emulsions protocols, (3) increasing bead density and/or moving to alternative clonal amplication strategies (other than emulsion PCR or ePCR), (4) extending software capabilities to allow SNP calls from our new sequencing raw data, (5) Dual Primer Emulsion PCR, and (6) diagnostic method exploiting one or more of the foregoing.
