The ipsogen BCR-ABL1 mbcr Controls Kit provides high, low, and negative controls for qualitative validation of RNA purification, reverse transcription, and quantitative PCR of BCR-ABL1 mbcr e1a2 transcripts using real-time PCR on the Rotor-Gene Q and other real-time PCR instruments. The controls are provided as individual vials containing 5 x 106 cells in preservative solution. The High p190 Control represents a high BCR-ABL p190 transcript level, the Low p190 Control corresponds to a reduced level of p190 expression compared to the high control level, and the Negative BCR-ABL p210 & p190 Control does not contain BCR-ABL p190 transcript.
