Application Abreviews Notes
WB 1/2000. Detects a band of approximately 15, 45 kDa (predicted molecular weight: 55 kDa).


  • Function

    RuBisCO catalyzes two reactions: the carboxylation of D-ribulose 1,5-bisphosphate, the primary event in carbon dioxide fixation, as well as the oxidative fragmentation of the pentose substrate in the photorespiration process. Both reactions occur simultaneously and in competition at the same active site.
  • Sequence similarities

    Belongs to the RuBisCO large chain family. Type I subfamily.
  • Post-translational

    The disulfide bond which can form between Cys-247 in the large chain dimeric partners within the hexadecamer appears to be associated with oxidative stress and protein turnover (By similarity). The disulfide bonds reported in 1RBO may be the result of oxidation during crystallization.
  • Cellular localization

    Plastid > chloroplast.

    Thank you for contacting us with your questions. We have only tested these antibodies under reducing conditions in WB. They may be suitable for use under non-reducing conditions as well, but this has not been validated in-house. I hope this information will be useful, but please let me know if you have any further questions and I'll be happy to help.

    Thank you for contacting us.  We have only tested these Peroxiredoxin antibodies under reducing conditions in WB.  They may be suitable for use under non-reducing conditions as well, but this has not been validated in house.  The unconjugated secondary antibody ab97141 will react with the primary antibody ab62391 and is suitable for use in WB.  You can detect this secondary antibody by either conjugating it with one of our EasyLink conjugating kits, or using an additional anti-goat secondary antibody.  Alternatively, you could use the equivalent HRP conjugated anti-Chicken IgY secondary antibody ab97150,  I hope this helps, please let me know if you need any additional information.
