Application & Selection
Use scenario
For time-resolved fluorescence lateral flow, TRFIA, multiplex assays and substitution evaluation.
Selection focus
Please provide sample type, assay platform, target sensitivity, current material combination and preferred specification for faster compatibility review.
Project support
JY Biotech can support sample discussion, substitution evaluation, method validation and supply coordination.
Communication
Specification, sample quantity, package, lot, lead time and documentation can be discussed according to the project stage.
Labeling and Stability Notes
Fluorescent nanobead projects should evaluate surface group, coupling condition, blocking system, storage buffer and conjugate pad release together. For weak signal, high background, aggregation or difficult resuspension, troubleshoot beads, labeling process and strip materials as one system.
Before coupling
Check particle size, surface group, buffer pH, ionic strength and centrifugation/resuspension conditions.
After coupling
Observe background, aggregation, ligand loss, storage buffer stability and signal decay after storage.
Strip validation
Validate sensitivity and background with treatment buffer, conjugate pad, NC membrane and reader window.
