Description

5-(n-Hexadecanoyl)Aminoeosin is a chemically modified derivative of eosin, a classic fluorescent dye, functionalized with a long-chain palmitoyl (hexadecanoyl) group. This modification significantly alters its solubility and lipophilicity, making it a valuable tool for specialized staining and labeling applications in biological research. It is particularly sought after by researchers and manufacturers in the life sciences and diagnostics sectors. The compound is supplied under strict quality control to ensure batch-to-batch consistency for sensitive experimental protocols.

Application

• Fluorescent Staining Agent: Used as a specialized stain for microscopic analysis of cellular and tissue structures, often in conjunction with other dyes.
• Bioconjugation & Probe Development: Serves as a fluorescent tag or hapten for labeling antibodies, proteins, or other biomolecules due to its reactive aminoeosin core.
• Lipid Membrane Studies: The hydrophobic hexadecanoyl tail facilitates incorporation into lipid bilayers and liposomes for membrane dynamics and trafficking research.
• Diagnostic Reagent Component: Employed in the formulation of specific histological stains and kits for pathology and clinical diagnostics.
• Photodynamic Therapy (PDT) Research: Investigated as a potential photosensitizer in preclinical studies for targeted therapies.
• Material Science Marker: Can be used to label or trace polymers and nanomaterials in development.
