Excellent biosample stabilization to improve molecular assay results, without changing clinical and research pathology workflows

Use TAG reagents to cut preanalytical variability of tissue, blood, and viral biosamples


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 Only (RUO)

For research use and COVID-19 test kit manufactures following validation per FDA EUA test VTM guidance.

  • 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
