Can bone marrow from leukemia patients with elevated numbers of white blood cells be processed with the PAXgene Bone Marrow RNA System?

Yes. We have tested the PAXgene Bone Marrow RNA System with bone marrow samples containing very high numbers of leukocytes. Bone marrow samples with higher leukocyte numbers are indicated by a highly viscous solution after addition of buffers BMR1 and BMR2 followed by incubation. These challenging samples are further diluted according to descriptions given in the protocol and do not lead to problems in the extraction procedure.
