(a) Concentration of the released protein versus time at different pH. (b) The results of SDS–PAGE analysis of in vitro released IgG up to 30 days and IgG stock solution. Lane 1:5 μl protein molecular weight standards; lane 2: blank; lane 3–13: 10 μl released protein samples collected after 0.5, 3, 6, 8, 10, 12, 15, 18, 22, 26 and 30 days, respectively; lane 14: 2.5 μl initial stock solution of IgG.
