The BCR-ABL Minor (p190) + ABL Quantification Control Material is a validated reference standard designed for accurate quantitative detection of BCR-ABL1 p190 fusion transcripts using real-time PCR (qPCR). The control contains defined levels of the BCR-ABL1 p190 target together with ABL as a reference gene, enabling assay calibration, standard curve generation, and normalized quantification. The inclusion of the ABL reference supports both absolute and relative quantification workflows, allowing laboratories to assess linearity, sensitivity, precision, and reproducibility. Suitable for assay development, validation, and routine performance monitoring. Quantitative measurement of BCR-ABL p190 is clinically relevant for diagnosis and molecular monitoring in acute lymphoblastic leukemia (ALL). Compatible with commonly used qPCR platforms and chemistries and integrates seamlessly into laboratory-developed test workflows. Designed for consistency and inter-run comparability. (RUO)
