LABELED ENZYME COMPOSITIONS, METHODS & SYSTEMS

摘要

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 labeled polymerase conjugates including a polymerase linked to one or more labels, wherein the conjugate has polymerase activity. Such conjugates can exhibit enhanced biological activity and/or superior detectability as compared to conventional labeled polymerases. 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.
