Cnpair supports the fight against gastric cancer by providing high-performance detection materials for Gastric Cancer Biomarkers: HP ( Helicobacter pylori), G17 (Gastrin-17), PGI (Pepsinogen I), and PGII (Pepsinogen II).
- Antigens for HP detection
Natural antigen Exceptionally high stability
Cnpair’s HP Antigen retains its native conformation with all critical epitopes intact, ensuring high stability. In thermal acceleration testing at 37°C for 7 days, it shows less than 20% signal deviation—outperforming international competitors.
- Antibodies for HP detection
>95% concordance with UBT Non-invasive detection
Cnpair’s highly specific antibodies achieve >95% concordance with urea breath tests (UBT). By precisely targeting antigenic epitopes, they effectively reduce false-positive and false-negative rates in testing, making them ideal for high-performance HP stool antigen detection on lateral flow (LF) assays.
- G17 Detection Materials
Excellent performance Strong correlation
Optimized for ELISA and CLIA platforms, G17 antibodies deliver outstanding performance. Rigorous validation on chemiluminescent AE application confirms exceptional correlation （R²＝ 0.9983， N=84) with leading international kits.
- PGI ＆ PGII Detection Materials
High stability Outstanding sensitivity
Cnpair’s antibodies are suitable for PGI & PGII serological test, delivering high stability and outstanding sensitivity. In rigorous chemiluminescence validation, Cnpair’s PGII antibody showed strong correlation （R² = 0.9781， N=40) compared to international company.
