What are the two types of proteome analysis ? how to they work?

(2D-page) electrophoresis , and chip on chip analysis : by first tagging of transcription factors with a protein fragment they immobilizing it with fixative agents, fragmenting dNA then Precipitation of DNA-protein complexes, then unbinding them. measurement of DNA enrichment when two extracts are co-hybridized on microarray(chip) each containing one DNA fragment likely to bind.
