Multi-Dtech™ – Multiplex Assay Kit
Multi-Dtech™ Multiplex Assay Kits are a cutting-edge solution designed for accurate and reliable detection of targeted biomarkers or molecules in biological samples. Multiplexing allows the detection of various biomarkers in a single assay.
Indeed, by combining different fluorophores with distinct emission spectra using appropriate detection methods, multiplex increases the throughput and efficiency of experiments. Our multiplexing technology is based on TR-FRET which is a fast, no-wash and low-interference technique.

TR-FRET immunoassay is an analytical method used for the detection and quantification of biomarker present in serum, plasma and cell supernatant. Our Bright-Dtech™ fluorescent nanoparticles bring a more sensitive and stable approach. In Bright-Dtech™ TR-FRET method, we design our nanoparticles and acceptors to detect different biomarkers with high specificity, sensitivity and at a low price.
By combining FRET and our technology, our Multi-Dtech™ Multiplex Assay Kits are an analytical method which can be used for the detection and the quantification of specific proteins, biomolecules, peptides, cytokines, hormones or antibodies, present in serum, plasma or cell culture supernatant. They present unique characteristics:
- Wide Dynamic Range: With its broad dynamic range, Multi-Dtech™ allow the quantification of both high and low concentrations of target molecules, ensuring accurate results across a wide range of sample concentrations
- High Performance: Multi-Dtech™ supress background noise and provide reliable data for your assays
- Ease of Use: Multi-Dtech™ are ready-to-use with clear step-by-step instructions, making it suitable for both experienced researchers and newcomers to multiplex assay kits.
- Fast: Based on TR-FRET technique, Multi-Dtech™ don’t requiere washing steps and thus reduce working time.
Multiplex Assay Kits find extensive application in various research areas, including:
- Biomarker identification and validation
- Drug discovery and development
- Protein-protein interactions
- Signal transduction studies
