Precision Power International has added certified instrument-power-protection systems (IPPS) for some of the most popular and recently released instruments.
Its customer base includes international and domestic distributors and representatives for Applied Biosystems and PerkinElmer, in addition to US-based researchers utilising Thermo Fisher LC-MS instrumentation.
The IPPS product additions include protection for the AB 3500 Genetic Analyzer range and the AB 7500 Fast Dx Real-Time PCR.
While PerkinElmer's ICP-OES and ICP-MS instruments are traditionally used in the inorganic and metal-analysis industry segments, they can also be used for the quantification of proteins and biomolecules by ICP-MS.
Protein-tagging reagents called metal-coded affinity tags (Mecat) have been introduced to label proteins quantitatively with metals, especially the lanthanide series.
The Mecat labelling allows for relative and absolute quantification of a number of proteins and other biomolecules, such as peptides.
The tagging reagent Mecat comprises a site-specific biomolecule-tagging mechanism with a strong chelate group that binds metals.
Mecat-labelled proteins are available for accurate quantification by ICP-MS down to very low attomol (10-18 mole) amounts of analyte.
ICP-MS Mecat methods yield at least two to three orders of magnitude more sensitivity than other mass-spectrometry-based quantification methods.
Laboratory managers can visit the PPI online catalogue to download Specification Data Sheets (SDS) as reference materials.
The SDSs include UL and CE-marked product applications for the various instruments.
The SDSs aid lab managers in determining space requirements, as well as providing certification for the instruments and accessories protected by specific catalogue numbers.
