Quantitation of Human Plasma and Breast Milk Thiamine Monophosphate (TMP) and Thiamine by Applying Impact™ Protein Precipitation Plate Technology with Gemini® 3 μm NX-C18 HPLC Columns

23 Dec 2014

Thiamine monophosphate (TMP) and thiamine were extracted from human plasma and human breast milk by performing a rapid protein precipitation using Impact Protein Precipitation Plates followed by HPLC analysis using a Gemini 3 μm NX-C18 100 x 3.0 mm HPLC column with fluorescence detection. Impact technology offers easy, fast protein removal while providing maximized recovery of the target analytes. The Gemini 3 μm NX-C18 HPLC column produced excellent chromatographic resolution, sensitivity, and high peak capacities.

Impact™ Protein Precipitation Plates

Phenomenex Inc

Impact™ protein precipitation plates with Solvent Shielding Technology™ offer a rapid and convenient way to remove proteins from plasma and tissue homogenate samples prior to analysis.The Solvent Shielding Technology design will withhold organic solvents above the filter membranes for up to 25 minutes, allowing for direct in-well precipitation upon sample addition. The precipitate is then filtered out via vacuum, centrifuge or positive pressure resulting in a clean, protein depleted extract.

UHPLC and HPLCHigh performance liquid chromatography (HPLC) and ultra high performance liquid chromatography (UHPLC), also known as UPLC, are analytical techniques used to separate, identify and quantitate components of complex mixtures including biological samples such as proteins and lipids as well as chemical mixtures of pesticides, drugs and oils. Both techniques are liquid chromatographic methods but differ by operating pressures (HPLC < 6000 psi < UHPLC ). Components of HPLC and UHPLC systems include columns, detectors, pumps, autosamplers and column heaters. Explore a range of UHPLC and HPLC columns for your specific sample needs including reverse phase, normal phase, ion exchange, HILIC, ion exclusion and size exclusion columns. For more specialized HPLC, explore FPLC, countercurrent LC and simulated moving bed systems.

The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.B VitaminsHuman PlasmaHuman plasma is the liquid component of blood, which carries blood components - nutrients, hormones, proteins, and waste - throughout the body. Plasma-based studies provide insights into biomarkers, immune responses, and disease mechanisms. Compare plasma handling tools and systems in our peer-reviewed product directory.
