Unbiased ('omic) Differential Expression Proteomics

Proteomics provides qualitative and quantitative information on the direct products of gene expression - proteins. Differential expression proteomics characterizes changes in the proteome due to biological challenges such as genotype, disease state and drug treatment. Additional applications include characterization of protein:protein interactions and biomarker identification.
