Do the samples require pretreatment before loading onto the instrument with the QIAsymphony PAXgene Blood RNA Protocol?

 Yes, samples with the QIAsymphony PAXgene Blood RNA Protocol have to be incubated at least 2 hours at room temperature (18– 22°C). Incubation of the PAXgene Blood RNA Tube overnight may increase yields slightly in some cases. Room temperature storage for up to 3 days may have no effect on the RNA profile. During the preparation of the RNA the manual pretreatment consists of a centrifugation and a pellet resuspension step (see the QIAsymphony PAXgene Blood RNA Kit Handbook).
