A very nutritious isotonic general-purpose medium with a low concentration of Glucose to stimulate early growth, Brain Heart Infusion Broth is suitable for the isolation of most micro-organisms including many fastidious organisms and, with enrichment as appropriate, is suitable as a base for blood culture medium. A phosphate buffer is incorporated to help neutralise any acids produced as a result of Glucose utilisation and thus maintain viability of the organisms. This particular formulation also has added Glycerol to act as cryopreservative if the medium is used for the long term frozen storage of microorganisms. NB: Organisms that produce large amounts of acid in the medium may overwhelm the buffering system and as a result ‘auto-sterilise’ the culture. -
MSS is a viral transport solution designed to facilitate collection and transport of viruses safely from site of sampling to a laboratory location at ambient temperatures. The medium is buffered to help maintain a pH of 7.1, and contains a metal ion chelator, a non-ionic surfactant and a chaotropic agent to ensure disruption of virus particles, denaturation of viral proteins and inactivation of nucleases that may destroy target nucleic acids. The resultant sample is suitable for virus identification by PCR analysis as well as other nucleic acid manipulations. MSS is designed to disrupt viral particles, denature viral proteins and, therefore, reduce the infection hazard during transport and laboratory processing. NB – BM1677 MSS has been validated only for use with the SARS-CoV-2 virus 2ml in self-standing M043 Tube • Aseptically filled • Red cap with swab capture point • Storage: 2-30°C • Store in the dark • Shelf life: 730 days • Samples collected in MSS are suitable for PCR analysis and other nucleic acid manipulations. • MSS is designed to disrupt viral particles, denature viral proteins, inactivate nucleases and reduce the infection hazard during transport and laboratory processing. -
This is a solution of novobiocin used as the selective agent in Modified Semi Solid Rappaport Vassiliadis Medium (BM4031) for the detection of motile Salmonella spp. -
The MSS (Molecular Sampling Solution) Swab Kit is designed to facilitate collection, inactivation and transport of patient specimens safely from the site of sampling to a laboratory location. The kit consists of a versatile sterile swab* for specimen collection and a self-standing polypropylene tube with swab capture cap containing Molecular Sampling Solution (MSS) inactivating transport medium. MSS is designed to disrupt microorganisms (including viruses and bacteria), release nucleic acids, denature proteins, and destroy nucleases. This reduces the infection hazard during transport and laboratory processing, as well as preserving nucleic acids for identification by PCR or other nucleic acid techniques. The stability of nucleic acids afforded by the MSS enables transport and storage in the 2-30°C range**. Viral nucleic acids remain stable in MSS at room temperature for at least 14 days. MSS (Molecular Sampling Solution) The MSS formulation is buffered to help maintain pH and contains a buffering agent (Tris), a metal ion chelator (EDTA), a non-ionic surfactant, and a chaotropic agent (guanidine isothiocyanate) to ensure disruption of microorganisms, denaturation of proteins, release of nucleic acids, and inactivation of nucleases that may destroy target nucleic acids. The resultant sample is suitable for target identification by PCR analysis as well as other nucleic acid techniques. SW0004 MSS Swab Kit cannot be used for cell culture-based diagnostic testing. *Not suitable for nasopharyngeal swabbing. **Must be stored in the dark.
