Metal-coded affinity tag
View on WikipediaMetal-coded affinity tag is a method used for quantitative proteomics by mass spectrometry that uses a metal chelate complex 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetate (DOTA) coupled to different lanthanide ions.[1][2] The metal complexes attach to the cysteine residues of proteins in a sample.
Proteomic analysis
[edit]For bottom-up proteomics, the proteins can be separated by two-dimensional gel electrophoresis and analyzed by matrix-assisted laser desorption/ionization (MALDI) or electrospray ionization mass spectrometry for relative quantification or by inductively coupled plasma mass spectrometry for absolute quantification. For top-down proteomics, the undigested labeled proteins are analyzed.
