Pressure-Temperature Nomograph Interactive Tool
Calculate a boiling point or pressure using the Antoine Equation: The Pressure-Temperature Nomograph is a graphical application of the Clausius-Clapeyron Equation, which assumes the heat of vaporization is a constant over a pressure range.
Standards for Detection and Enumeration of Listeria monocytogenes and Listeria spp. in the food chain
ISO published revised EN ISO 11290-1 and EN ISO 11290-2 standards in 2017. In Part 1, a horizontal method for the detection of Listeria monocytogenes and Listeria spp. is specified, and in Part 2, the enumeration of these organisms in
RNA Stabilization at Room Temperature in RNAstable®
Quantitative RT-PCR analysis demonstrates successful amplification of RNA templates that were stored dry in RNAstable® for 29 months at room temperature and under accelerated aging conditions equivalent to 12 years of room temperature storage.
Whole Genome Amplification: Extraction Protocol - Blood Card
Whole Genome Amplification: Extraction Protocol - Blood cards provide the convenience of archiving small volumes of blood. However, many times genomic DNA from these samples is limited, which may hinder the researcher’s ability to perform downstream analysis. This protocol provides
