Application examples

Application examples Application example

western blot using anti-PR-2 antibodies

10 µg of total protein from Arabidopsis thaliana mature leaves were extracted with 8M UREA and were separated on 12 % SDS-PAGE and blotted 1h to PVDF. Blots were blocked with 5% Milk in TBS-T 0,05% 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. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once for 15 min and 3 times for 5 min in TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, from Agrisera AS09 602) diluted to 1:10 000 in TBS-T/Milk 5% for 1h at RT with agitation. The blot was washed as above and developed for 5 min with ECL according to the manufacturers instructions. Exposure time was seconds 60 seconds.

Background

Background PR-2 (Pathogenesis-related protein 2) is involved in the defence of plants against pathogens. This protein has a catalytic activity and is hydrolysing of (1->3)-beta-D-glucosidic linkages in (1->3)-beta-D-glucans, EC=3.2.1.39. Alternative names:Glucan endo-1,3-beta-glucosidase, acidic isoform,(1->3)-beta-glucan endohydrolase, Beta-1,3-endoglucanase, Beta-1,3-glucanase 2
