WebThe RQ is your fold change compared to the calibrator (untreated sample, time zero, etc.). The calibrator has a RQ value of 1. All samples are compared to the calibrator. A RQ of 10 means that this gene is 10 times more expressed in sample x then in the calibrator sample. A RQ of 0,1 means that the gene is 10 times less expressed.
