Pre-Coated Beads: No Biotin Interference
TruQuant pre-coated streptavidin magnetic beads are prepared by saturating streptavidin binding sites with biotin-labeled antibodies, forming a stable and fully occupied surface before sample introduction. It prevents free biotin present in patient samples from binding to the beads and generating false signals. Pre-coated beads effectively reduce biotin interference, lower background noise, and improve assay specificity and reliability, particularly in samples from patients taking biotin supplements or high-dose therapies.
Oriented Coupling: Maximum Binding Efficiency
Our oriented coupling technic enables antibodies to be immobilized on magnetic beads or solid surfaces in a controlled and uniform orientation, ensuring that the antigen-binding Fab regions are fully exposed and accessible. This approach maximizes effective binding capacity, improves reaction kinetics, and reduces steric hindrance. Oriented coupling enhances assay sensitivity and reproducibility, lowers background variability, and delivers more consistent performance across runs.
Reagent Stability Optimization: Consistent and Reliable Performance
TruQuent reagents is formulated with stability-optimized conditions to ensure homogeneity and reliability in the liquid phase throughout storage and use. By minimizing aggregation, precipitation, and phase separation, this approach preserves reagent homogeneity, reduces background variability, and maintains consistent reaction kinetics. TruQuant stability enhanced reagents deliver improved reproducibility, lower CV, and reliable performance over the full shelf life.
Recombinant Expression: Stable Cell line, Reliable Assay Performance
Recombinant DNA technology enables the controlled production of TruQuant assay's critical reagents using stable expression systems, ensuring consistent molecular structure and reliable performance. This approach improves batch-to-batch consistency, enhances reagent stability, and supports long-term supply scalability. As a result, TruQuant assays demonstrate improved reproducibility and robustness across manufacturing and lifecycle use.
