Abstract: Disclosed herein are conjugates comprising a biomolecule linked to a label that have biological activity and are useful in a wide variety of biological applications. For example, provided herein are polymerase-nanoparticle conjugates including a polymerase linked to a nanoparticle, wherein the conjugate has polymerase activity. Such conjugates can exhibit reduced aggregation and improved stochiometries wherein the average biomolecule:nanoparticle ratio approaches or equals 1:1. Also disclosed herein are improved methods for preparing such conjugates, and methods and systems for using such conjugates in biological applications such as nucleotide incorporation, primer extension and single molecule sequencing.

Abstract: The present disclosure provides compositions, methods, kits, systems and apparatus that are useful for nucleic acid polymerization. In particular, modified polymerases and biologically active fragment thereof are provided that allow for nucleic acid amplification. In one aspect, the disclosure relates to modified polymerases useful for nucleic acid sequencing, genotyping, copy number variation analysis, paired-end sequencing and other forms of genetic analysis. In some aspects, the disclosure relates to modified polymerases useful for the generation of nucleic acid libraries or nucleic acid templates for use in various downstream processes. In some aspects, the disclosure relates to the identification of homologous amino acid mutations that can be transferred across classes or families of polymerases to provide novel polymerases with altered catalytic properties. In some aspects, the disclosure provides modified polymerases having enhanced catalytic properties as compared to a reference polymerase.
