PsbX is a small (4 kDa) and very hydrophobic subunit of PSII, Immunoblots from SDS-gels (especially with high loading) may show higher molecular weight signals from PsbX not fully detached from other subunits of PSII, The use of 15% SDS-PAGE gels with 2-4 M urea is recommended when working with this antibody,For an image of antibody detection in a western blot application see Garcia-Cerdan et al. (2008).
Plant PsbX is a small nuclear encoded 4kda protein associated with photosystem II that is present in all species of oxygen-containing organisms.
