Saliva, Swab and Stool Samples

Saliva, swab, and stool sample collectors are vital in research, offering non-invasive, convenient, and cost-effective methods for gathering biological samples.

Saliva collectors provide an easy way to obtain samples rich in biomarkers like hormones, enzymes, and genetic material, making them essential for psychological, endocrinological, and infectious disease research.
Swab collectors are crucial for collecting samples from the nasal passages, throat, or skin, particularly in diagnosing respiratory infections and conducting genetic studies.
Stool sample collectors play a key role in microbiome research, enabling the study of gut bacteria and their impact on health and disease.

A critical aspect of these collectors is the preservation of DNA and RNA integrity. Maintaining the stability of genetic material is essential for accurate analysis, particularly in genetic and microbiome studies. Proper preservation ensures that the samples yield reliable data, which is crucial for understanding complex biological processes and disease mechanisms.

Viral Transport Medium

The liquid Amies is ideal for transport of clinical swab specimen.

The presence of sodium thioglycolate favors the growth of a broad range of pathogens. Calcium, Sodium, Potassium, and Magnesium chlorides elongate the proliferation of pathogens and increases the permeability of bacterial cells. The Sodium and Potassium phosphates work as a pH buffer, to maintain the ideal pH for stabilisation of the sample.

Additional to Amies transport medium, we also offer other VTM, CDC (WHO formulation) medium and PBS (phosphate buffered saline) medium and several swab kits.

PSP® Salivagene products

SalivaGene Collector

The SalivaGene Collector includes the collection devices for assisted sample collection in plastic bags for lower cost per sample. This product is offered in packages of 50 collectors or as bulk (as requested) for high sample numbers. e.g. for clinical studies. The barcode labelled primary tube is also compatible with all common robotic platforms.

SalivaGene Comfort Set

The SalivaGene Comfort Set includes the collection components in a blistered package with barcode labelled primary tubes, prefilled with the stabilisation buffer for easy-to-use buccal cell saliva swab collection and DNA protection, optimal in high-throughput processing, e.g. for clinical studies. The barcode labelled tube is compatible with common robots.

SalivaGene Collection Module II

The SalivaGene Collection Module II is a simple, alternative version for saliva sample collection and stabilisation using a liquid DNA stabilisation buffer (DNA is also stable for 12 months at room temperature).
