Can specific types of white blood cells be enriched from a PAXgene Bone Marrow RNA Tube prior to the RNA isolation?

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.
