Fig. 2From: Optimization of skeletal protein preparation for LC–MS/MS sequencing yields additional coral skeletal proteins in Stylophora pistillataDistribution of proteins numbers according of the purification methods. Distribution of all proteins (SOM and ISOM combined) by purification methods (a). SOM and ISOM distribution by acetone precipitation methods (ACT; b). SOM and ISOM distribution by centrifugation and ultrafiltration method (CF; c). Note that CF methods yielded more proteins in total.
