Characterization of antibodies against Arabidopsis p24 proteins. Protein extracts were obtained from membranes of Arabidopsis cell suspension cultures (C) or Arabidopsis roots (R), as described in the Materials and methods, and analysed by SDS–PAGE (14% acrylamide) and western blotting with antibodies against the p24δ9 N-terminus and p24β3 N-terminus, or with the corresponding pre-immune sera. Western blotting with antibodies against p24δ5 and p24β2 (Montesinos et al., 2012) is also shown. Note the slightly different electrophoretic mobility of p24δ5/p24δ9, p24β2, and p24β3.
