From: Significance analysis of microarray for relative quantitation of LC/MS data in proteomics
Volcano plot for pH5av and pH7av. The blue diamonds, pink squares, and red triangles represent proteins with fold change of less or equal to 2, greater than 2 but lees or equal to 3, and greater than 3 respectively. The x marks indicate that a protein is found significant (p < 0.05) by the t-test based on triplicate protein relative abundances without referring to peptide information. See text for more details.
