Fig. 2From: Proteomic analysis of sputum reveals novel biomarkers for various presentations of asthmaSputum proteomics data from healthy controls and asthma patients. Heat map of selected protein expression in induced sputum of asthma patients and health controls. Expression patterns in selected proteins are visually presented as expression matrix using a relative scale ranging from -10 (blue) to 15 (red) (a). Principal components analysis (PCA) of protein expression in three asthmatic patients and matched-control subjects. CON, blue; CA, light green; CVA, purple; CTVA, red (b).
