Maine Molecular Quality Controls Inc Birlinn BCR-ABL1 p210 IS Control Panel C240

The Birlinn BCR-ABL1 p210 IS Control Panel C240 is intended for use as an assayed external quality control to monitor the performance of in vitro laboratory nucleic acid detection and quantification of BCR-ABL1 (p210) fusion gene using molecular test systems, and allows monitoring of assay performance reporting on the international scale. Each component of the panel contains an increasing concentration of BCR-ABL1 RNA transcript mixed with a fixed concentration of ABL1 RNA transcript to produce three levels 0.01%, 0.1%, and 1%. The %IS values provided are traceable to World Health Organization Reference Panel, NIBSC code 09/138, and are assigned to each lot of the Birlinn BCR-ABL1 p210 IS Control Panel C240 according to NIBSC Instructions for Use. This control has been tested and is compatible with assays on multiple platforms, including AB Analitica, QIAGEN, Bioclarma, and BIO-RAD. Reach out to MMQCI to ask about compatibility with your specific assay.
