Description

Texas Red-Methacrylate CAS NO 386229-75-0 is a reactive fluorescent dye derivative designed for covalent labeling and polymer conjugation. This compound is valued for its ability to introduce a bright, photostable Texas Red fluorophore into biomolecules and synthetic polymers via its methacryloyl group. It is essential for researchers and manufacturers in life sciences and advanced materials who require site-specific fluorescent tagging. The product enables the creation of labeled probes for imaging, diagnostics, and functional polymeric materials.

Application

• Fluorescent Probe Synthesis: Covalent labeling of antibodies, proteins, peptides, and oligonucleotides for fluorescence microscopy (e.g., confocal, super-resolution) and flow cytometry.
• Polymer Functionalization: Incorporation into acrylic and methacrylic polymers via copolymerization to create fluorescently tagged hydrogels, nanoparticles, and micelles for drug delivery tracking and material science studies.
• Diagnostic Assay Development: Manufacturing of fluorescent conjugates used in ELISA, immunohistochemistry (IHC), and in situ hybridization (FISH) kits.
• Bioconjugation & Crosslinking: Serving as a heterobifunctional reagent for creating fluorescent crosslinkers or modifying surfaces for biosensor applications.
• Cell and Tissue Labeling: Preparation of vital stains or fixable dyes for long-term cellular and histological imaging experiments.
