•HBV Detection Material•

Cnpair HBV detection materials advantage

Our product portfolio includes HBsAg, HBcAb, HBeAg, and HBV Pre-S1, enabling accurate identification of various stages of HBV infection. In a clinical evaluation involving 138 mutant strains, Cnpair successfully detected 107 strains (77.5%), demonstrating industry-leading performance in mutation detection.

•HIV Detection Material•

Cnpair HIV detection materials advantage

Cnpair’ s materials are designed for use in both third and fourth-generation HIV assays, including reagents for HIV-1/2/O antibodies and p24 antigen, effectively reducing the diagnostic window period. In BBI seroconversion panel testing, Cnpair demonstrated 100% concordance with leading global companies in Chemiluminescence Immunoassay (CLIA) platform.

•HCV Detection Material•

Cnpair HCV detection materials advantage

Cnpair uses NS3 and CORE antigen for coating and detecting. NS3 is a key protease in the HCV virus replication, while CORE is a major structural protein containing multiple immunodominant epitopes. The chimeric design covers multiple key HCV epitopes, reducing the risk of missed detection and providing a powerful tool for the early detection and intervention of HCV infection.

•TP Detection Material•

Cnpair TP detection materials advantage

Cnpair provides multiple antigen combination options, including chimeric antigens and fragmented antigens (15KD, 17KD, 47KD):
1.Chimeric pairing: streamlines the process while maintaining sensitivity.
2.Chimeric coating and mixed fragment detecting: multi-epitopes signal amplification, fewer false positives.
3.Chimeric pairing and supplementary fragments: enhances targeted epitopes recognition, and overcome interference from complex samples.


These combinations ensure both sensitivity and specificity, as well as stability, with a storage condition of 2-8℃ for 15 months and a positive signal deviation of ≤±20%.
