Fig. 5From: Methodology: an optimized, high-yield tomato leaf chloroplast isolation and stroma extraction protocol for proteomics analyses and identification of chloroplast co-localizing proteinsThe spectrum of normalized spectral abundance factors (NSAFs) for CIPs with predicted subcellular locations. CIPs predicted to be localized in the cytosol, peroxisome, nucleus, mitochondrion, and endomembrane system are shown. The number of times a protein was detected was plotted against the protein’s NSAF. Each circle represents a single protein. Protein identities, NSAF values and number of times detected can be found in Additional file 4: Table S4Back to article page
