Bright-Dtech™ 575 – Dy (Yellow)
Coupled to Biotin

Description

Bright-Dtech™ Kits – Ready-to-Use Fluorescent Nanoparticles

With Bright-Dtech™, we offer an innovative solution for sensitive fluorescence-based detection using easy-to-use protocols across a wide range of molecular and cellular biology applications. Our fluorescent lanthanide nanoparticles combine high signal intensity, long-lifetime emission, and excellent photostability, supporting sensitive and reliable detection.

Biotinylated detection reagents are widely used in streptavidin-based assays, enabling high-affinity binding to streptavidin-conjugated molecules such as antibodies, peptides, or nucleic acids. Bright-Dtech™ 575 – Dy (Yellow) coupled to biotin offers a versatile and highly sensitive solution for your applications, allowing easy integration into existing biotin-streptavidin detection systems.

Thanks to their characteristic lanthanide emission spectra, Bright-Dtech™ 575 – Dy (Yellow) can be combined with other Bright-Dtech™ nanoparticles to enable multiplex detection of multiple targets in the same sample, expanding diagnostic capabilities while minimizing spectral overlap.

 

How to Use Bright-Dtech?

Recommended dilutions may vary depending on the assay format, detection system, and sample type. The following ranges are provided as a general starting guideline:

Immunoassays (e.g., TR-FRET, TR-FLISA, Western blot, dot blot)

• Dilution range: 1:10 to 1:1000
• Optimize according to signal intensity, background, and detection system sensitivity

 

Cell-based assays (e.g., flow cytometry, immunofluorescence, imaging)

• Dilution range: 1:5 to 1:20 (or higher)
• Optimization may depend on instrument sensitivity, sample type, staining conditions, and required signal-to-background performance

 

We strongly recommend performing pilot titration experiments to determine the optimal working dilution under your specific assay conditions.
