Bright-Dtech™ 545 – Tb (Green)
– For LFIA –
Standard

Description

With Bright-Dtech™, we offer an innovative solution for achieving higher detection sensitivity with easy-to-use protocols, specifically optimized for Lateral Flow Assays (LFIA). Our ultra-efficient fluorescent nano-moleculesprovide unmatched brightness, ensuring superior performance in rapid diagnostic applications (Watch our video on Youtube).

Bright-Dtech™ is a patented technology based on lanthanide nanoparticles, delivering exceptional sensitivity and stability for fluorescent-based LFIA applications. By integrating Bright-Dtech™ nanoparticles, we significantly enhance the performance of conventional detection methods, making assays more precise and reliable.

This biologically inert product serves as a standard control, allowing you to evaluate and optimize the performance of our nanoparticles on your membranes and buffers without biomarker detection.

 

How to Use Bright-Dtech ?

Recommended dilutions vary based on the type of assay, detection system, and sample type. Below are general guidelines:

Lateral Flow 

• Dilution range: 1:2 to 1:100
• Adjust according to signal intensity, background, and detection system sensitivity

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