Description

Irdye 800 Nhs is a near-infrared (NIR) fluorescent dye functionalized with an N-hydroxysuccinimide (NHS) ester for covalent labeling of biomolecules. This compound matters for researchers and developers requiring high-sensitivity, low-background detection in complex biological matrices, particularly for in vivo imaging and advanced diagnostic assays. It is needed by professionals in the biotechnology, pharmaceutical, and medical diagnostics industries for applications such as antibody conjugation, protein labeling, and the development of novel imaging probes.

Application

• Antibody-Dye Conjugate Synthesis: Covalent attachment to primary amines for creating targeted imaging agents.
• Protein and Peptide Labeling: Fluorescent tagging of biomolecules for tracking, quantification, and interaction studies.
• In Vivo Fluorescence Imaging: Development of NIR probes for deep-tissue imaging in preclinical research.
• Diagnostic Assay Development: Key component in lateral flow assays, ELISA, and other immunoassays requiring NIR detection.
• Biomolecule Immobilization: Functionalizing surfaces (e.g., microarrays, biosensors) with fluorescent tags for detection.
• Cell Labeling and Tracking: Conjugation to targeting ligands for specific cell population imaging.
