A. SDS-PAGE gel lanes showing purified Sso0001 and Sso1391 proteins. Concentrated samples of Sso0001 and Sso1391 had an olive-green appearance. B. The Sso0001 protein eluted from a calibrated superpose 12 column in one major symmetrical peak with a size corresponding to a molecular weight of 175 kDa.
