Description

Janelia Fluor 585, Se is a specialized selenium-containing fluorophore from the renowned Janelia Fluor dye family, designed for advanced bioimaging and super-resolution microscopy. Its core value lies in its exceptional photostability and brightness in the far-red to near-infrared spectrum, enabling researchers to visualize biological processes with unprecedented clarity and minimal background interference. This compound is essential for life science researchers, diagnostic developers, and pharmaceutical companies engaged in high-resolution cellular imaging, single-molecule tracking, and the development of novel fluorescence-based assays and probes.

Application

• Super-Resolution Microscopy (STORM/PALM): As a photoswitchable or photoconvertible dye for techniques requiring precise single-molecule localization.
• Single-Molecule Tracking (SMT): For labeling and long-term tracking of proteins, lipids, or other biomolecules within live cells due to high photon output.
• Bioconjugation & Probe Development: Serving as a critical component in synthesizing antibody-dye conjugates, FISH probes, or activity-based sensing probes.
• Intracellular & In Vivo Imaging: Leveraging its far-red emission for deeper tissue penetration and reduced autofluorescence in live-cell and small animal imaging.
• Multiplexed Imaging: Used in combination with other Janelia Fluor dyes for simultaneous visualization of multiple cellular targets.
• DNA/RNA Labeling: Incorporation into nucleic acid sequences for advanced genomic visualization and sequencing applications.
• Material Science & Sensor Development: Application in developing fluorescent sensors and functional materials that respond to specific environmental stimuli.

Quality Control

Every batch of Janelia Fluor 585, Se is produced and controlled under stringent quality management systems to ensure consistency and performance for critical research applications. We employ advanced analytical techniques, including HPLC, NMR, and mass spectrometry, to verify identity, purity, and the absence of interfering impurities. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below under desiccant. This compound is hygroscopic (moisture-sensitive) and strictly light-sensitive (protect from all light exposure). Allow the sealed vial to equilibrate to room temperature before opening to minimize moisture condensation. For long-term storage, keep under an inert atmosphere such as argon or nitrogen.
