Confirmed reactivity: Plasmodium falciparum - Application Examples
-
Western blot 
10 ng of purified, recombinant pf FNR from Plasmodium falciparum (1), partially purified ferredoxin from culture ofPlasmodium falciparum (2), 1.4 ng of purified, recombinant ferredoxin fromPlasmodium falciparum (3) with 2x SDS-sample buffer (+ 2ME) for SDS-PAGE and denatured with 4X SDS buffer at 95°C for 5 min. Samples were separated on 10% SDS-PAGE and blotted 1h to PVDF membrane. Blot was blocked with 3 % skim milk/TBS-T, 1h/RT with agitation. Blot was incubated in the primary antibody at a dilution of 1: 1000 in TBS-T for 1h/RT. The antibody solution was decanted and the blot was washed 4 times for 10 min in TBS-T at RT with agitation. Blot was incubated in matching secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:10 000 in for 1h/RT with agitation. The blot was washed as above and developed with a chemiluminescent detection reagent, following manufacture's recommendation.
Immunofluorescence
Trophozoit and shizont stages of Plasmodium falciparum were stained with the anti-ferredoxin antibodies (right panels, red color). Nuclear DNA was stained with DAPI (middle panels, blue color). Dark spots in bright field microscopy (left panels) are hemozoin pigment.
Plasmodium falciparum parasitic cells were fixed with 4 % paraformaldehyde in PBS on ice for 30 minutes, spread onto slides and air dried. Permabilization was done with: PBS with 1 % Triton X-100. Blocking: 3 % BSA in PBS for 3 h.
Secondary antibody: Cy3 conjugated, 1: 1000
Primary antibody: 1: 100 - Background
-
Background: Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions. - Product Citations
