Description

Sulforhodamine 101 Cadaverine TFA Salt is a high-purity, functionalized fluorescent dye derivative, essential for advanced bioconjugation and labeling applications. This compound is specifically engineered to provide a reactive amine handle (via the cadaverine linker) for covalent attachment to biomolecules, enabling the creation of bright, photostable probes. It is a critical reagent for researchers and manufacturers in life sciences, diagnostics, and pharmaceutical development who require precise and stable fluorescent markers for imaging, assay development, and cellular tracking.

Application

• Bioconjugation and Probe Synthesis: Primary use for labeling antibodies, proteins, peptides, and oligonucleotides with a bright, far-red fluorescent tag.
• Fluorescence Microscopy & Imaging: Creation of custom fluorescent probes for super-resolution microscopy, confocal imaging, and live-cell tracking studies.
• Diagnostic Assay Development: Key component in developing fluorescent immunoassays (FLISA), lateral flow tests, and in-situ hybridization (FISH) kits.
• Flow Cytometry: Used to synthesize antibody-dye conjugates for high-sensitivity cell surface marker detection and analysis.
• Material Science & Sensor Fabrication: Incorporation into polymers, nanoparticles, and biosensors for optical sensing and detection platforms.
• Pharmaceutical Research: Tool compound for drug targeting studies, pharmacokinetics, and biodistribution imaging in preclinical research.
