(FLEXIBLE LIQUID BIOPSY) blood collection tube (BCT)

For Research Use Only (RUO). Designed to stabilize cell-free nucleic acids (cfDNA / cfRNA), total RNA, gDNA, intact cells, and proteins, in a single tube.

Compare TAG FLEX-LB to EDTA, Streck, and PAXgene RUO BCTs | benchmark data available

  • Room temperature stabilization of whole blood samples
  • One tube for many biomarker targets
  • Thermo-protective for flexible shipping, storage, and lab processing
  • Cost-effective 10 mL RUO BCT
  • Stabilizes cell-free DNA (cfDNA) & cell-free RNA (cfRNA) for up to 7 days
  • Preserves & conserves plasma content
  • Works with vacuum manifolds and bead extraction protocols


non-toxic tissue fixative | no protein crosslinking | use the same lab protocols as formalin | designed to optimize molecular tests

TAG-1 is a Class 1 general reagent pursuant to 21 CFR 864.4010  designed to directly replace formalin for tumor tissue fixation.  TAG-1 is non-toxic, odorless, does not crosslink proteins, and is designed to improve the quantity and quality of DNA, RNA, and cellular proteins compared to FFPE tissue, while providing excellent cellular morphology, staining, IHC and FISH test pathology results.

Features and Benefits

  • Designed to be used for storage and transport of fresh tissues, or a
    direct replacement for formalin in tissue processing
  • Use the same lab protocols as formalin in tissue processing
  • Designed to optimize molecular tests, excellent for molecular assays such as DNA-seq, RNA-seq, FISH, etc.
  • A non-toxic tissue fixative
  • No protein crosslinking, designed to better preserve tissue morphology
  • Unique formulation with wide IP protection 


 TAG-NGPM+  (Next Generation Pathogen Media)

For research use and pathogen test kit manufactures following validation per FDA.

  • Does not require a cold chain for storage or transport – RNA is kept stable at room temperature for up to 28 days.
  • Keeps RNA stable in freeze-thaw
  • Designed for nasopharyngeal, oropharyngeal, and saliva test kits
  • Designed to better preserve RNA fragments and proteins in samples to enable more accurate tests
  • Made in the USA
  • Validated in Lab Developed Tests
  • Rapidly inactivates Virus – reduce the risk of virus exposure to clinical staff and laboratory personnel.  See Rutgers University research results.
  • Safe to use with standard laboratory decontamination reagents such as bleach
  • Inhibits bacteria and fungal contamination 
  • Compatible with leading platforms including Hologic Panther and Roche Cobas 
  • Lower price and higher value than any other VTM, UTM and ITMs 
  •  High volume fulfillment available now
  • Also available as a standard virus-culturing transport media (VTM) w/o inactivation (TAG-NGPM™)
