This article delves into two core metrics for molecular diagnostic kits: sensitivity and stability. From definitions and assay principles to multidimensional evaluation methods and practical optimization guidelines, it comprehensively reveals how scientists control kit quality, avoid experimental failures, and ensure the reliability of test results, laying the foundation for precision medicine.

No sample purification is required! Qihengxing Bio's direct amplification PCR/qPCR technology utilizes an inhibitory polymerase and optimized buffer system to achieve direct amplification from whole blood, achieving a sensitivity of 10 copies/μL. It is compatible with multiplex assays and various anticoagulants (EDTA/heparin). It covers early cancer screening and pathogen detection, advancing point-of-care (POCT) applications. Clinical validation has demonstrated an R² correlation >0.98 with nuc

Qihengxing joins hands with industry, academia and research to open a new chapter of development

Qihengxing's product - StarPure High-Resolution Agarose (FS-E1001) contributed spark power to this research with its excellent performance!

This in-depth analysis covers the entire SNP detection kit development process, from disease target screening (GWAS/ClinVar databases), technology selection (qPCR/NGS/arrays), clinical sample validation, and Class III medical device filing. This section covers high-throughput assay optimization, anti-interference testing, and regulatory compliance.

StarLighter Blood Direct Amplification PCR Kit - Accurately amplify blood samples frozen for 20 months, and perform 6-plex PCR simultaneously

Starting a new journey, measuring the world, shining the future, 2025 Qihengxing will be completely upgraded

Qihengxing's flagship product, StarLighter HotStart Taq Pro PCR Mix (FS-P5001), helped Liu Long's team at Jiangnan University publish their study, "A cross-species inducible system for enhanced protein expression and multiplexed metabolic pathway fine-tuning in bacteria," in Nucleic Acids Research (IF 16.6). This study developed a cross-species inducible system that significantly improved protein expression and metabolic pathway regulation, providing a key tool for synthetic biology and metaboli
