product information

Catalase is an enzyme found in most living organisms which is catalazying decomposition of hydrogen peroxide to water and oxygen. In plant cells catalase is found in peroxisomes. This enzyme is involved in photorespiration and symbiotic nitrogen fixation.


KLH-conjugated peptide chosen from know plant catalase sequences including Arabidopsis thaliana isoforms: catalase-1 (Q96528, At1g20630), catalase-2 (P25819, At4g35090), catalase-3 (Q42547, At1g20620);

Host Rabbit
Clonality Polyclonal

western blot using anti plant catalase antibody

10 µg of total protein from Arabidopsis thaliana Col0 (1), Cat2-(Col0) (2), Ler0 (3), Cat2-(Ler0) (4), Zea mays (5), Oryza sativa (6), Brassica oleracea (7), Nicotiana bentamina (8) were extracted with 60mM Tris pH 6.9, 10mM DTT, 20% glycerol, 1mm PMSF were separated on 12.5% SDS-PAGE and blotted 1h to PVDF. Blot was blocked with 3% skim milk in PBS+0.05% Tween20 for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 1 000 for 1h at RT with agitation in the same buffer. The antibody solution was decanted and the blot was rinsed briefly three times, then washed 3 times for 5 min in PBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, Agrisera, AS09 602) diluted to 1:50 000 in 3% skim milk in PBS+0.05% Tween20 for 1h at RT with agitation. The blot was washed as above and developed for 1 min with Western Lightning Plus-ECL ( PerkinElmer )according to the manufacturers instructions. Exposure time was  5min. in ChemiDoc XRS+ (Biorad ).
