On March 19th, Qihengxing successfully held its first distributor technical training session of 2025. Forty-eight distributors nationwide gained in-depth knowledge of nucleic acid extraction processes, PCR amplification optimization protocols, and the core advantages of its test kits. Dr. Qin Chubin provided scenario-based case studies on the application of molecular diagnostic technology, facilitating the upgrade of terminal services. Qihengxing's year-round empowerment plan has been launched,

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

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

The Qihengxing Blood Direct qPCR Kit is designed specifically for blood samples, eliminating the need for complex nucleic acid extraction steps and enabling qPCR amplification with simple lysis. It is suitable for a variety of sample types, including fresh blood, blood stored at 4°C, blood frozen at -20°C, and EDTA-anticoagulated blood. Compatible with Taqman probe-based assays and SNP detection, it offers simple operation and accurate results, completing the entire process from blood sample ana
