Purification of Gcd from C. symbiosum. (A) SDS-PAGE analysis on Gcd after the monomeric avidin agarose affinity chromatography. The compositions of the bands were identified by MALDI-TOF MS. (B) SEC profile of chemically fixed and unconcentrated Gcd. The SEC was performed with Tris–HCl, pH 7.0, 100 mM NaCl, 0,05% DDM.
