Analytical Biochemistry

The Analytical Biochemistry resource was established to support and facilitate collaborative cancer research between the various disciplines at the Center by providing chemical analyses which contribute to understanding chronic diseases in our population. It also assists in the determination of the nature or structure of biological molecules as well as the quantification of those compounds. The facility is equipped with essential instruments needed to perform analytical chemistry, and modern, state-of-the-art technology for difficult-to-measure and ultra-low concentrated compounds.

The laboratory is conducting analyses of clinical analytes, lipid soluble plasma antioxidants, serum carotenoids and vitamins in support of several NIH-funded projects, including research on many types of cancer. The resource constantly updates its assays to utilize the latest technology. For example, blood Vitamin C is now measured by liquid chromatography with electrochemical detection which is faster and more accurate relative to the traditional colorimetric method. HPLC-based assays are transitioning to smaller column diameters, faster flow rates and the use of ultra-high pressure liquid chromatography to provide better sensitivity, faster analysis time and less waste generation. Both two tandem MS systems (triple-quadrupole TSQ Ultra, Thermo Scientific) and two high-resolution accurate-mass orbitrap systems (Q- Exactive, Thermo Scientific) are available. The laboratory conducts assays based on liquid chromatography mass spectrometry (LC/MS) extensively. This core conducts assays based on liquid chromatography mass spectrometry (LC/MS) extensively. One tandem MS systems (TSQ Ultra, Thermo) and two accurate-mass orbitrap system (Q-Exactive, Thermo) are available. These high-end MS instruments offer improved sensitivity, selectivity and accuracy for many analytes. This resource has also added ELISA assays including multiplexed operations using Luminex technology and most recently also Macular Pigment Optical Density (MPOD) readings using a model Macular Metrix II instrument acquired in 2016 from Macular Metrics, Rehoboth, MA.
