Figure 4

SDS-PAGE of redispersed cream fraction from deproteinized nonammonia FNRL with EDTA complexes. FN-SH samples were incubated with 0.1 wt% EDTA in different forms in the presence of 1 wt% SDS for 1 h. Lane 1: FR-SH, lane 2: mixture of FR-SH and EDTA-4Na without centrifugation, lane 3: washed FR-SH with SDS followed by centrifugation, lane 4: FR-SHDPNR-EDTA, lane 5: FR-SHDPNR-EDTA-1Na, lane 6: FR-SHDPNR-EDTA-2Na, lane 7: FR-SHDPNR-EDTA-3Na, and lane 8: FR-SHDPNR-EDTA-4Na.
