RNA samples were extracted from 8 cell line mixtures expressing various BCR-ABL1 transcript levels.     ///    Quality of RNA was consistent between laboratories and met the criteria requested for quantification of BCR-ABL1 transcripts.     ///    "Therefore, we evaluated the minicapsule-based innovative process developed by Imagene (Evry, France) for implementing DNA and RNA controls designed for clonality assessment of lymphoproliferations and BCR-ABL1 mRNA quantification, respectively.
