Abstract: Provided herein are materials and methods for performing bioluminescent assays using a bifunctional probe. In particular, the present disclosure provides compositions and methods for detecting and/or quantifying a biomolecule and/or assaying a cellular process associated with the biomolecule using a bifunctional probe capable of binding the biomolecule and generating a bioluminescent and/or fluorescent signal.

Abstract: Conjugates comprise a drug or probe, a cell binding agent, and a quinone-containing linker. The quinone-containing linker may be reduced intracellularly to trigger release of the drug or probe. These conjugates may selectively deliver a drug or probe to a site of action of interest for local release of the active drug or probe.

Abstract: Provided herein are reagents and methods for incorporating modified nucleotides into DNA and detecting DNA synthesis. In particular, haloalkyl-modified nucleobases are provided for incorporation into nucleic acids for detection by bioluminescent binding agents.

Abstract: Provided herein are compositions, systems, and methods for assessing modulators of immune checkpoints. In particular, artificial antigen presenting cells (aAPCs) and immune effector cells are provided to assess the potency of test agents to inhibit immune checkpoints.

Abstract: Disclosed is a method and corresponding kit for assaying the presence, activity, or both, of an enzyme classified within an enzyme classification selected from the group consisting of EC 2.7.1, EC 3.1.3, and EC 3.1.4. The method generally includes the steps of reacting an enzyme with a substrate for a time sufficient to yield phosphorylated or dephosphorylated product; contacting the product with a binding matrix, whereby product is adhered to the matrix; and then analyzing the matrix for presence of, amount of, or both the presence and the amount of the product fixed to the matrix, whereby the presence, the activity, or both the presence and activity of the enzyme can be determined.
