Labeled enzyme compositions, methods and systems
First Claim
1. A labeled polymerase conjugate, comprising:
- a polymerase linked to at least three optically detectable dye labels, wherein the at least three optically detectable dye labels are linked to one or more biotin acceptor peptide sequences of the polymerase, and wherein the conjugate has polymerase activity and emits upon continuous excitation a total photon count of at least 106 photons before irreversibly photobleaching.

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 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.
