Provided herein, among other things, are a variety of methods for transposase-mediated tagging and amplification of short DNA fragments, e.g., between about 150 bp and 1.5 Kb in length. In some aspects, the method includes tagging the DNA fragments with a first primer sequence using barcoded transposases followed by a primer extension reaction to introduce a second primer sequence, e.g., using random or gene-specific primers. Kits for performing this method are also provided.

Transposase-random priming DNA sample preparation

A method for making an asymmetrically-tagged sequencing library is provided. In some embodiments, the method may comprise: obtaining a symmetrically-tagged library of cDNA or genomic DNA fragments, hybridizing a tailed first primer to the 3' sequence tag of the library and extending the same to produce primer extension products, and amplifying the primer extension products using a pair of tailed primers to produce asymmetrically-tagged library.

Method for making an asymmetrically-tagged sequencing library

The invention relates to the generation and characterization of stable MMLV reverse transcriptase mutants. The invention also discloses methods of using stable MMLV reverse transcriptase mutants.

Mutant reverse transcriptase and methods of use

The invention provides mutants of DNA polymerases having an enhanced resistance to inhibitors of DNA polymerase activity. The mutant polymerases are well suited for PCR amplification of targets in samples that contain inhibitors of wild-type polymerases.

Thermostable type-A DNA polymerase mutant with increased resistance to inhibitors in blood

The present invention provides mutants of DNA polymerases having an increased rate of incorporation of nucleotides into nucleic acids undergoing polymerization and having an enhanced resistance to inhibitors of DNA polymerase activity. The mutant polymerases are well suited for fast PCR applications, for PCR amplification of targets in samples that contain inhibitors of wild-type polymerases, and for fast PCR amplification of samples containing DNA polymerase inhibitors. In exemplary embodiments, the mutants are mutants of Taq DNA polymerase.

Thermostable type-A DNA polymerase mutants with increased polymerization rate and resistance to inhibitors

The present invention relates to a method for identifying a nucleotide at a predetermined location on a target polynucleotide. The method involves single nucleotide extension reaction comprising an oligonucleotide primer comprising a first sequence and a second sequence or a tag. The method may further comprises a probe which hybridizes to the second sequence or an anti-tag molecule which interacts with the tag, where the hybridization or interaction causes a detectable signal transfer which is indicative of the identity of the nucleotide base at the predetermined location. The invention further provides compositions and kits for performing the subject method of the invention.
