Application examples

Application examples Application example

0.5 µg of total leaf protein isolated with Agrisera Protein Eextraction Buffer (AS08 300) from Arabidopsis thaliana (1), Spinacia oleracea (2), Zea mays (3), Hordeum vulgare (4), Solanum tuberosum (5), Pisum sativum (6) were separated on 4-12% NuPage (Invitrogen) LDS-PAGE and blotted 45 min (30V) to nitrocellulose. Filters where blocked 1h with 2% low-fat milk powder in TBS-T (0.1% TWEEN 20) and probed with AS07 218 (1:20 000, 1h) and secondary anti-rabbit (1:20000, 1 h) antibody (HRP conjugated) in TBS-T containing 2% low fat milk powder. Antibody incubations where followed by washings in TBS-T (15, +5, +5, +5 min). All steps were performed at RT with agitation. Signal was detected with chemiluminescence using a Fuji LAS-3000 CCD (300s, high sensitivity).

Background

Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase) catalyzes the rate-limiting step of CO2 fixation in photosynthetic organisms. It is demonstrably homologous from purple bacteria to flowering plants and consists of two protein subunits, each present in 8 copies. In plants and green algae, the large subunit (~55 kDa) is coded by the chloroplast rbcL gene, and the small subunit (15 kDa) is coded by a family of nuclear rbcS genes.
