FAQ-2506
What RNA yields are expected with the PAXgene Bone Marrow RNA System?
Bone marrow samples are extremely heterogeneous, consisting of varying amounts of cells, tissue, and solid matter. RNA yields are highly donor-dependent and can vary greatly from sample to sample as well as between replicates from the same donor due to sample-intrinsic heterogeneity.
In a study of 295 bone marrow samples, yields of RNA isolated from 2 mL human bone marrow were between 2.0 and 44.7 µg (5-95% quantiles, mean = 15.8 µg, median = 11.0 µg).

PAXgene Bone Marrow RNA Kit
The PAXgene Bone Marrow RNA System consists of PAXgene Bone Marrow RNA Tubes, for stabilization, storage, and transportation of bone marrow, and the PAXgene Bone Marrow RNA Kit, for silica-membrane-based RNA isolation and purification in a spin-column format. Bone marrow samples are collected using standard medical practices, with commonly used anticoagulants. A 2 ml sample is immediately transferred into a PAXgene Bone Marrow RNA Tube, which stabilizes the RNA in the sample for storage at room temperature, refrigerated, or frozen. RNA can be purified days later using the PAXgene Bone Marrow RNA Kit or archived for several months at –20°C or –70°C.
