3 results about "Affinity labeling" patented technology

The present application relates to an assay method using affinity crosslinking of DNA-linked ligands to proteins to enable small molecule screening and determination of apparent affinity constants of ligands to the proteins. This method has been applied to determine 96 compounds' dissociation constants to a protein target simultaneously, and directly determine a compound's IC50 against five protein targets concurrently in crude cell lysates. Additionally, this approach was used to screen a Library of Pharmacologically Active Compounds (LOPAC) library against dihydrofolate reductase (eDHFR), enabling the discovery of a novel eDHFR inhibitor (IC50=7.9 μM). An assay kit and the method of uses are within the scope of this disclosure.

Provided herein are novel compounds, compositions, that can used as clickable, photo-affinity labeling (PAL) probes methods for use in screening NAD+ binding proteins.

The disclosure provides methods to assemble genomes of eukaryotic or prokaryotic organisms. The disclosure provides methods for haplotype phasing and meta-genomics assemblies. The disclosure provides a streamlined method for accomplishing these tasks, such that intermediates need not be labeled by an affinity label to facilitate binding to a solid surface. The disclosure also provides methods and compositions for the de novo generation of scaffold information, linkage information, and genome information for unknown organisms in heterogeneous metagenomic samples or samples obtained from multiple individuals. Practice of the methods can allow de novo sequencing of entire genomes of uncultured or unidentified organisms in heterogeneous samples, or the determination of linkage information for nucleic acid molecules in samples comprising nucleic acids obtained from multiple individuals.
