  • Application Examples
  • Western blot using anti-Caleosin antibodies

    Arabidopsis thaliana senescent leaves were freshly extracted with 2x SDS-sample buffer (+ 2ME) for SDS-PAGE (crude extract) and denatured with 4X SDS buffer at 95°C for 5 min. 10 µg of protein was loaded/well and were separated on 15-20 % SDS-PAGE and blotted 1h to PVDF membrane. Blot was blocked with 3 % skim milk/TBS-T, 1h/RT with agitation. Blot was incubated in the primary antibody at a dilution of 1: 5000 in TBS-T for 1h/RT. The antibody solution was decanted and the blot was washed 4 times for 10 min in TBS-T at RT with agitation. Blot was incubated in matching secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:10 000 in for 1h/RT with agitation. The blot was washed as above and developed with a chemiluminescent detection reagent, following manufacture's recommendations.
  • Background
  • Background: Caleosin3 encodes a calcium binding protein whose mRNA is induced upon treatment with NaCl, ABA and in response to desiccation. mRNA expression under drought conditions is apparent particularly in leaves and flowers. Isoform of caleosin with a role as a peroxygenase involved in oxylipin metabolism during biotic and abiotic stress. Involved in the production of 2-hydroxyoctadecatrienoic acid. The peroxygenase has a narrow substrate specificity thus acting as a fatty acid hydroperoxide reductase in vivo. Protective role to fungus pathogen has been indicaed. Expression is very low in young leaves and high in senescent leaves.
