Figure: Purification of IgG using Protein A Sepharose (Cat. # 6501): (a) SEC analyses of IgG purified from rabbit serum. 1 ml rabbit serum in Protein A IgG Binding Buffer was loaded on 1 ml Protein A Sepharose & IgG was purified according to the protocol. 200 µl of starting sample (A) (serum) and purified IgG (B) were analyzed on Superdex 200 HR 10/30 column at 0.5 ml/min in 50 mM Tris, 0.25 M NaCl pH 7.5. (b) SDS-PAGE (10%) of purified IgG under reduced conditions. Lane 1: Marker, Lane 2: IgG fraction (5 µg).
