Description

Cellhunt Orange Cmtmr [5-(6)-(((4-Chloromethyl)Benzoyl)Amino)Tetramethylrhodamine] is a reactive, fluorescent dye derivative of tetramethylrhodamine (TAMRA). This compound is valued for its high fluorescence quantum yield and photostability, making it an essential tool for advanced labeling and detection. It is primarily needed by researchers and manufacturers in the life sciences, diagnostics, and biotechnology sectors for applications such as fluorescence microscopy, flow cytometry, and the development of fluorescent probes and sensors.

Application

• Fluorescent Labeling of Biomolecules: Covalent conjugation to proteins, antibodies, peptides, and nucleic acids for detection and imaging studies.
• Live-Cell and Fixed-Cell Imaging: Used as a vital stain or as part of labeled probes for fluorescence microscopy (e.g., confocal, super-resolution).
• Flow Cytometry & FACS: Employed in the development of fluorescent antibodies and other reagents for cell sorting and analysis.
• FRET (Förster Resonance Energy Transfer) Probes: Serves as an acceptor or donor dye in the construction of molecular beacons and biosensors.
• Diagnostic Assay Development: Key component in the formulation of fluorescent lateral flow assays, ELISA, and other in vitro diagnostic kits.
• Polymer and Material Science: Incorporation into nanoparticles, hydrogels, and polymers to create functional, traceable materials.

Quality Control

Our Cellhunt Orange Cmtmr is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and MS for structural confirmation, and spectrophotometry for fluorescence properties. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and performance specifications is provided with every shipment to ensure compliance with research and diagnostic-grade standards.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a desiccated environment. This product is hygroscopic (moisture-sensitive) and light-sensitive. Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake.
