Test of SOD antisera specificity. Twenty-five
micrograms of total protein from Arabidopsis rosette leaves and 12 ng
of the purified 6× His-tagged MSD1, FSD1, CSD1, CSD2, and CSD3
proteins were run on SDS-PAGE and subjected to immunoblot analysis.
Postions of molecular-mass markers are listed on the left of each row
of gels. The antisera and dilution (v/v) used are listed at the bottom
of each gel. AP, Affinity-purified antiserum.
