First commercial lab-on-a-chip Lab-on-a-chip devices have gone commercial with the introduction of Hewlett-Packard's HP 2100 Bioanalyzer. Based on Callper Technologies' LabChip, the system provides sample preparation, microfluidics, and biochemical analysis of DNA on a microchip. Assays are available for analyzing restriction digests with DNA fragments 100-12,000 bases long; determining size and concentration information for DNA fragments 100-7500 bases long; ;nd checking the quality of various RNA products. The complete kit has a list price of $18,000 and includes a chip reader, a computer outfiited with application-specific software, and various LabChips and reagents.
Reagent for Determination of H2O2 A5020 Oxo[5, 10, 15, 20-tetra(4-pyridyl)porphinato]titanium(IV)
100mg
$105.75
The Titanium-porphyrin complex 1 is useful for spectrophotometric determinination truce amounts of H2O2. The colorimetric method is based on the formation of the Tiianiumorphyrin-H2U2 complex 2, which is relatively unaffected by interferences from reducing substances. The molar absorptivity of the complex is 190,000M cm , which is much igher than other coloring reagents. The lower limits of detection are 10 nM by the batch method or 1 pmol per injection by flow injection analysis(FIA). The combination of colorimetry and FIA has been successfully used in the ullramicro analysis of H2O2 featuring rraid dnalysis and digh precision.
