Product Infomation
Product Name Fluorescent Calibration Microspheres (EX/EM=300-500 nm/530±5 nm)
Catalog Number FLM-CB-001
Description High-stability fluorescent microspheres maintain undiminished fluorescence intensity even after hundreds of consecutive excitation cycles, fully meeting testing requirements.This specially formulated fluorescence-stable control microsphere satisfies the optical specifications of time-resolved fluorescence chromatography systems while exhibiting intense visible coloration, enabling clear visualization of T and C lines.By immobilizing these fluorescent microspheres on an NC membrane followed by drying to prepare a fluorescence quality control card, the performance of fluorescence analyzers can be reliably monitored, effectively eliminating inter-instrument and intra-instrument variability.
Applications Embedded as a calibration reference in the quality control card, it generates a standard curve through stable and adjustable fluorescent signals, thereby standardizing quantitative detection; utilizing multicolor fluorescent coding, it enables simultaneous monitoring of multiple quality control indicators on a single card; and through its interference-resistant performance, it evaluates the test card’s suitability for complex samples; These fluorescent quality control microspheres are compatible with time-resolved fluorescent immunoassay platforms and are suitable for applications in fluorescent immunoassay, labeling, tracing, detection, biosensors, and microfluidic biochips. Clinical applications include thyroid function testing (e.g., TSH, T3, T4), sex hormone testing (e.g., FSH, LH, HCG, etc.), tumor marker testing (e.g., AFP, CEA, PSA, etc.), infectious disease testing (e.g., HBsAg, HBsAb, etc.), inflammatory disease testing (e.g., SAA, CRP, etc.), and cardiovascular disease testing (e.g., cTnI, NT-proBNP, etc.).
Features High fluorescence stability; high fluorescence intensity; narrow emission wavelength and broad excitation wavelength; stable manufacturing process with minimal batch-to-batch variation.
