The PAXgene Tissue System consist of the PAXgene Tissue Fixation and Stabilization products for collection, transport and storage of human tissue specimens and dedicated purification kits to isolate nucleic acids.

The PAXgene Tissue RNA/miRNA Kit isolates total RNA, including miRNA, from tissues fixed in PAXgene Tissue FIX Containers. The RNA and miRNA can be isolated from either PAXgene Tissue-fixed (PF) or PAXgene Tissue-fixed, paraffin-embedded (PFPE) tissue.
