Sample collection & preservation

Saliva, buccal sample and stool sample collection & stabilization

Flexible Sampling: Solutions for Storing and Shipping Your Samples in RT

For field-, home- and clinic-based sampling. Compatible with most downstream chemistries for DNA and RNA isolation.

Saliva samples

Isohelix GENEFIX™ CE-IVD saliva DNA collection device & stabilization buffer: DNA is stored for at least 5 years in RT. Read more

Isohelix GENEFIX™ saliva DNA microbiome collection device: Instant stabilization of the microbiome. The DNA is stored in RT at least 1 year. Read more

Buccal samples

Isohelix DNA/RNA buccal swabs (for skin, surface, tissue sampling etc.) are suitable for human and veterinary use. Store the swaps in RT for 2 years with BuccalFix Stabilization kit or 3,5 years with Dri-Capsules.


NEW Isohelix™ RapiDri™ Buccal Swabs with Self-Drying Pouch Moisture wicking RapiDri™ Pouch preserves the DNA swab for 3 months at room temperature. Includes also a barcoded sealing label. Read more

Stool samples

NEW StoolFix gut microbiome collection device includes a swab and a prefilled 2 ml stabilization buffer tube that protects the DNA integrity and maximizes DNA yield for months at room temperature. Read more

Stabilization of cells & tissues

Anacyte’s CellCover is a non-toxic formulation and ready to use solution for complete protecting of RNA, DNA and protein and the cellular shape integrity in human and animal solid tissues, including tumors, white blood cells and cultured cells (adherent, suspension, spheroids). It was developed for fast “one step” stabilizing of biomolecules in tissue specimens and cultured cells.

Cells Treated with CellCover Maintain Their Native State

CellCover is the only reagent that allows parallel storage of proteins, RNA, and DNA in their cellular context, maintaining cellular shape integrity without chemical crosslinking.

  • Stabilize RNA, DNA and proteins simultaneously for several days
  • Cells maintain close to in vivo morphology without chemical crosslinking of biomolecules allowing straight forward RNA isolation
  • No freezing necessary

CellCover is compatible with morphological analyses and staining procedures, with immunocytochemistry and flow cytometry. Cells treated with CellCover maintain morphology for several days. Epitopes are protected and can be stained later. RNA degradation is inhibited leading to great results in RNA sequencing or single cell sequencing experiments.


Furthering downstream applications (as for instance):
Batch and Single Cell Analysis, FISH, RNA Sequencing, Flow cytometry/ FACS Microarray analysis, Northern blotting, Immunocytochemistry, NGS, Western blotting, Immunohistochemistry, PCR … and many others
