The HPV-39 (L1, E6/E7) Synthetic Quantification Control is a calibrated reference standard designed for quantitative detection of Human Papillomavirus type 39 using real-time PCR (qPCR). The control contains defined copy numbers of synthetic DNA fragments representing the L1 and E6/E7 regions, enabling accurate assay calibration and viral load estimation. This quantitative control supports standard curve generation, assay validation, and routine performance monitoring, allowing assessment of key analytical parameters including linearity, sensitivity, precision, and reproducibility. Coverage of both L1 and E6/E7 regions ensures suitability for assays targeting either structural or oncogenic HPV regions. Quantitative assessment of HPV-39 is increasingly relevant for risk stratification, clinical research, and assay harmonization. The synthetic design ensures high reproducibility, long-term stability, and safe handling. Compatible with commonly used qPCR platforms and chemistries.(RUO)
