Technology
Mass spectrometers coupled in series. The targeted compound is selectively ionized, and its characteristic ions are separated from others in the mixture in the first mass spectrometer. The selected primary ions are then decomposed by collision, and from the resulting products the final mass analyzer selects secondary ions characteristic of the targeted compound. Tandem mass spectrometry can achieve specificities and sensitivities equivalent of those of methods such as radioimmunoassay and gas chromatography/mass spectrometry, while performing analyses in much shorter times.

Indicators
This gene is involved in signal transduction and negative regulation of apoptosis. It also plays a role in glucose transport, glycogen synthesis, protein synthesis and neuronal survival.
Indicators
This gene plays a role in glucose homeostasis and the inhibition of apoptosis.
Indicators
This gene is involved in signal transduction and the inhibition of apoptosis.
Indicators
This gene is involved in apoptosis, DNA repair and cell cycle regulation.
Indicators
This gene is involved in cell cycle checkpoints and DNA recombination.
Indicators
This gene is involved in cell organization/biogenesis and the inhibition of apoptosis.
Tests
A BUN, or blood urea nitrogen test, measures the amount of urea nitrogen in your blood. Urea nitrogen is a waste product that forms as your body breaks down proteins. It's carried in your blood and then removed by your kidneys when you urinate (pee).
