Multimer glycosylated nucleic acid binding protein conjugates and uses thereof
First Claim
1. A method for detecting the presence, absence or amount of nucleic acid containing beta-D-glucosyl-hydroxymethylcytosine and/or a nucleic acid containing beta-D-glucosyl-hydroxymethyluracil in a sample, comprising:
- contacting the sample that may contain nucleic acid containing beta-D-glucosyl-hydroxymethylcytosine and/or a nucleic acid containing beta-D-glucosyl-hydroxymethyluracil with a multivalent multimer conjugate comprising two or more polypeptides selected from the group consisting of a full-length native J-DNA binding protein (JBP) or substantially identical polypeptide thereof, a J-DNA binding fragment of a full-length native JBP or substantially identical polypeptide thereof and a polypeptide comprising the J-DNA binding domain of a JBP or substantially identical polypeptide thereof, wherein each polypeptide in the multimer is directly conjugated to a scaffold, wherein the scaffold is an antibody or an antibody fragment, which polypeptides specifically interact with a nucleic acid containing beta-D-glucosyl-hydroxymethylcytosine and/or a nucleic acid containing beta-D-glucosyl-hydroxymethyluracil; and
determining the presence, absence or amount of the multimer that specifically interacts with the nucleic acid in the sample, whereby the presence, absence or amount of nucleic acid containing beta-D-glucosyl-hydroxymethylcytosine and/or a nucleic acid containing beta-D-glucosyl-hydroxymethyluracil in a sample is determined.

Abstract
The technology relates in part to multimer conjugates comprising a scaffold linked to two or more polypeptides that specifically interact with a nucleic acid containing beta-D-glucosyl-hydroxymethylcytosine or beta-D-glucosyl-hydroxymethyluracil. The scaffold can be chosen from an antibody, an antibody fragment, a multimerized binding partner that interacts with a binding partner counterpart in each of the polypeptides, a polymer, and a polyfunctional molecule. The polypeptides can be from a kinetoplastid flagellate organism and may comprise a full-length native or modified protein or a fragment thereof that specifically interacts with the beta-D-glucosyl-hydroxymethylcytosine and/or the beta-D-glucosyl-hydroxymethyluracil in the nucleic acid. The conjugates provided herein can be used to detect the presence, absence or amount of beta-D-glucosyl-hydroxymethylcytosine and/or beta-D-glucosyl-hydroxymethyluracil-containing nucleic acid in a sample.
