Blood Collection and RT Preservation of cfDNA, gDNA, CTC, RNA


All-In-One Liquid Biopsy Tubes

HemaSure-OMICS tubes from Mawi DNA Technologies are a groundbreaking product for ambient collection, stabilization, and transportation of whole blood samples. HemaSure-OMICS enables isolation of cfDNA, gDNA, CTC, and RNA from the same sample. Collected cells are maintained intact, making them also suitable for FACS analysis.

So far blood stabilization technologies contained hazardous formaldehyde or formaldehyde-like fixatives that stabilize cfDNA or Circulating Tumor Cells (CTC) or RNA but not all three from the same sample. Moreover, the maximum shelf life of stabilized CTC and RNA at room temperature was no more than 72 hrs.

To overcome these hurdles and enable widespread and efficient collection and analysis of whole blood Mawi DNA Technologies has developed the HemaSure-OMICS Collection Tube products:

  • Non-toxic stabilization of whole blood; free of formaldehyde or formaldehyde-like ingredients
  • cfDNA, gDNA (both up to 14 days), CTC (up to 8 days), and RNA (up to 8 days) are stabilized at room temperature in the same blood tube
  • Available in 3, 6, and 9 mL plastic vacuum-filled blood collection tubes as well as a 250µl microtainer for blood drops for easy shipping and durability
  • Compatible with manual or automation-enabled kits for purification of cfDNA, gDNA, RNA, and CTC from whole blood
