A surface plasmon resonance-based system to genotype human papillomavirus

Area of Science:

• Biotechnology
• Molecular Diagnostics
• Virology

Background:

• Human papillomavirus (HPV) is a major cause of cervical cancer.
• Accurate HPV genotyping is crucial for risk stratification and patient management.
• Existing genotyping methods may have limitations in sensitivity, specificity, or throughput.

Purpose of the Study:

• To introduce and evaluate a novel Surface Plasmon Resonance (SPR) based system, W2600, for human papillomavirus (HPV) genotyping.
• To assess the analytical performance of the W2600 system in detecting a comprehensive panel of HPV genotypes.
• To compare the W2600 system's performance against a gold standard method for HPV genotyping.

Main Methods:

• Development of the W2600 system utilizing Surface Plasmon Resonance (SPR) technology.
• Detection of 24 known HPV genotypes, encompassing 16 high-risk and 8 low-risk types.
• Analytical validation using HPV DNA from 560 liquid cervical cytology specimens.

Main Results:

• The W2600 system detected 24 HPV genotypes with high sensitivity and specificity.
• Concordance with clonal sequence analysis was 99% (kappa = 0.98, P < 0.001).
• No cross-hybridizations were observed, and all 16 high-risk HPV genotypes were identified.

Conclusions:

• The SPR-based W2600 system demonstrates high sensitivity and specificity for HPV genotyping.
• The W2600 system provides an effective and reliable approach for HPV detection in clinical settings.
• This novel system has the potential to improve cervical cancer screening and management.
