Time-Resolved Fluorescence (TRF) technology represents a significant leap forward in achieving  enhanced sensitivity and reduced background in the field of bioanalysis and diagnostics. Our TRF particles incorporate the unique photophysical properties of lanthanide ions, specifically europium (Eu), terbium (Tb), and samarium (Sm). These rare earth elements exhibit long-lived fluorescence, allowing for a significant delay between excitation and emission. This crucial time delay effectively eliminates short-lived background fluorescence, leading to dramatically improved signal-to-noise ratios.

Key Features & Benefits:

• Distinct Emission Wavelengths: Leverage the unique spectral signatures of our lanthanide-doped particles for multiplexing capabilities:

• Excitation at 360 nm, with a bright and distinct emission at 615 nm.

• Optimized for excitation at 430 nm, emitting a sharp peak at 613 nm.

• Excitable at 323 nm, providing a characteristic emission at 562 nm.

• Enhanced Sensitivity: The inherent long fluorescence lifetimes of lanthanides minimize interference from short-lived autofluorescence, enabling the detection of low-abundance targets.

• Reduced Background: Time-resolved detection virtually eliminates prompt fluorescence and scattering, resulting in cleaner and more reliable data.

• Wide Size Range: Our TRF particles are available in a comprehensive range of sizes to suit diverse application needs, from cellular labeling to high-throughput screening. (20 nm ~100 um)

• High Quality and Uniformity: Manufactured under stringent quality control, our microspheres exhibit exceptional monodispersity and consistent fluorescence intensity, ensuring reproducible results.

• Versatile Applications: Ideal for a wide array of applications, including:

• High-Sensitivity Immunoassays

• Nucleic Acid Detection

• Cell-Based Assays

• Receptor-Ligand Binding Studies

• Flow Cytometry

• Microscopy
