•HBV Detection Material•
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’ 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 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 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%.
