The Nutritional Biomarker Laboratory at the Harvard T.H. Chan School of Public Health has more than 30 years of expertise in the analysis of antioxidants and fatty acids in blood, tissues, and foods backed by external quality monitoring programs administered by the National Institute of Standards and Technology (NIST), the American Oil Chemists’ Society (AOCS), and the Centers for Disease Control and Prevention (CDC). More recently we have added a blood lipid panel, 25-OH vitamin D EIA assay, tyrosol and hydroxytyrosol in urine and plasma, and various ELISA-based assays. We are skilled at the development of new assays that are amenable to our instruments and are happy to discuss projects beyond the scope of our standard panels.
"BioTek Instruments have developed the Synergy™ HT Multi-Mode Microplate Reader. This plate reader for fluorescence, absorbance and luminescence measurements was designed with an emphasis on superior performance in all detection methods. Unlike many multi-mode microplate readers, the Synergy HT utilizes a unique dual-optics design."
