Discovering cell surface proteins' behavior
Date:2/12/2013

l industry. "As membrane proteins, glycoproteins are biologically important," explains Sun, who is fluent in Mandarin and English, and is originally from Mailand China.

"They mediate cells' communication to their environment, thus governing a plethora of cellular processes and functions, including growth, development, immunity and aging. "Understanding how membrane proteins adapt to better protect themselves will help us design better, less toxic drugs to treat diseases."

Backgrounder: Understanding surface cell proteins

Mass spectrometry (MS) is an analytical technique that measures the mass-to-charge ratio of charged particles.[1] It is used for determining masses of particles, for establishing the elemental composition of a sample or molecule, and for elucidating the chemical structures of molecules, such as peptides and other chemical compounds.

High-performance liquid chromatography (sometimes referred to as high-pressure liquid chromatography), HPLC, is a chromatographic technique used to separate a mixture of compounds in analytical chemistry and biochemistry with the purpose of identifying, quantifying or purifying the individual components of the mixture. HPLC is considered to be the most frequently used instrumental technique in analytical chemistry.

HPLC has many uses including medical (e.g. detecting vitamin D levels in blood serum), legal (e.g. detecting performance enhancement drugs in urine), research (e.g. separating the components of a complex biological sample, or of similar synthetic chemicals from each other), and manufacturing (e.g. during the production process of pharmaceutical and biological products).
