Figure 3. Purification of Agrin-Nterm by gel chromatography.

Figure 3

Recombinant protein isolated by Ni affinity chromatography (seeFig. 2.) was chromatographed on a AKTA purifier 10 System using a Superdex gel filtration column (HiLoad 10/300 Superdex 200 GL) and fractions containing pure Agrin-Nterm (horizontal bar) were pooled. Lane a of the insert shows SDS-PAGE of Agrin-Nterm of the pooled factions of AKTA chromatography, lane b indicates the pattern of the Low Molecular Weight Calibration Kit (Amersham Pharmacia Biotech, Uppsala, Sweden; Mr values: 14,400, 20,100, 30,000, 45,000, 66,000, and 97,000).
