The JAK2 Exon 14 V617F Quantification Control Material is a validated reference standard designed for quantitative detection of the JAK2 V617F mutation using real-time PCR (qPCR). The control contains defined levels of the JAK2 V617F mutant sequence, enabling accurate assay calibration and quantitative performance assessment. This material supports standard curve generation, assay validation, and routine quality control, allowing laboratories to evaluate analytical sensitivity, precision, and reproducibility. Quantitative measurement of JAK2 V617F allele burden is clinically relevant for diagnosis, risk stratification, and disease monitoring in myeloproliferative neoplasms (MPNs). The control is compatible with commonly used qPCR platforms and chemistries and integrates easily into laboratory-developed test workflows. Designed for consistent performance and reliable longitudinal monitoring. Intended for research and laboratory use. (RUO)
