2'3'-cGAMP photo affinity probe

2'3'-cGAMP photo affinity probe enables covalent capture of cGAMP-binding proteins under UV-activated chemoproteomics workflows. Researchers use it to immobilize transient or weak interactions from cell lysates or purified protein mixtures, supporting downstream identification by enrichment and mass spectrometry. The probe's photoactivatable handle is designed for crosslinking upon irradiation, allowing users to convert soluble binding events into stable conjugates that can be isolated and analyzed.

2'3'-cGAMP photo affinity probe supports affinity-based labeling of cGAMP signaling components in chemical biology studies. Investigators commonly apply it to map interaction networks around the cGAMP pathway by comparing labeling patterns across stimulation conditions, genetic backgrounds, or inhibitor treatments. The probe format is particularly useful when the experimental goal is to retain binding information through covalent capture prior to pull-down and analytical readout.

2'3'-cGAMP photo affinity probe is used for target engagement and ligand-binding validation in mechanistic reagent development. Teams developing modulators of cGAMP-related enzymes and binding proteins can use the probe as a competitive tool to assess whether candidate ligands occupy the same binding sites, translating binding competition into a measurable labeling signal after UV activation and enrichment. This workflow is frequently integrated with immunoblotting, gel-based detection, or proteomic identification depending on the available instrumentation.

2'3'-cGAMP photo affinity probe also fits into biomolecular interaction mapping for nucleotidyl transferase and adaptor-associated complexes. In studies that require capturing protein complexes that associate with cyclic dinucleotides, the probe can be used to stabilize interaction states during sample processing. After crosslinking and isolation, researchers can interrogate labeled proteins to build interaction models that complement functional assays and orthogonal binding experiments.
