Deproteinization of Nonammonia and Ammonia Natural Rubber Latices by Ethylenediaminetetraacetic Acid

<div>SDS-PAGE of redispersed cream fraction from deproteinized ammonia FNRL with EDTA complexes. FN-NH<sub>3</sub> was incubated with 0.10 wt% of EDTA in different forms for 1 hour at room temperature in the presence of 1 wt% SDS. Lane 1: FR-NH<sub>3</sub>, lane 2: mixture of FR-NH<sub>3</sub> and EDTA-4Na without centrifugation, lane 3: washed FR-NH<sub>3</sub> with SDS followed by centrifugation, lane 4: FR-NH<sub>3</sub>DPNR-EDTA, lane 5: FR-NH<sub>3</sub>DPNR-EDTA-1Na, lane 6: FR-NH<sub>3</sub>DPNR-EDTA-2Na, lane 7: FR-NH<sub>3</sub>DPNR-EDTA-3Na, and lane 8: FR-NH<sub>3</sub>DPNR-EDTA-4Na.</div>
