Additional information

Additional information

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).
