KLH-conjugated synthetic peptide which is a part of part of the glutamine synthetase/guanido kinase superfamily catalytic region chosen from various available sequences, including Arabidopsis thaliana GLN2, UniProt: Q43127, TAIR: AT5G35630
47 | 44-45 kDa
0.5 µg of protein from Arabidopsis thaliana total leaf fraction (1), 5 µg of protein fromSpinacia oleracea chlorplast enriched fraction (2), molecular weight markers (MagicMarkTM,Invitrogen) (M), the same samples as in 1 and 2 but after peptide neutralisation assay, e.g. incubation of the antibody with 100 mM excess of peptide used to elicit andt-GLN2 antibody (4,5), extracted with PEB (AS08 300), were separated on 4-12% NuPage (Invitrogen) LDS-PAGE and blotted 1h to PVDF (Millipore). Filters were blocked 1h with 2% low-fat milk powder in TBS-T (0.1% TWEEN 20) and probed with anti-GLN2 antibody (AS08 296, 1:5 000, 1h) and secondary anti-rabbit (1:20000, 1 h) antibody (HRP conjugated) in TBS-T containing 2% low fat milk powder. Antibody incubations were followed by washings in TBS-T. All steps were performed at RT with agitation. Blots were developed for 5 min with ECL Advance detection reagent according the manufacturers instructions (GE Healthcare). Images of the blots were obtained using a CCD imager (FluorSMax, Bio-Rad) and Quantity One software (Bio-Rad).

Glutamine synthetase (GLN or GS) is one of the key enzymes involved in nitrogen metabolism of plants. It catalyses the synthesis of glutamine from glutamate and ammonia in an ATP-dependent reaction. There are two general classes of glutamine synthetase in plants: GLN1, a cytosolic form and GLN2, a chloroplastic form. GLN2 is encoded by a single gene and is highly abundant in mesophyll cells of leaves for the assimilation of ammonia produced from photorespiration and the reduction of nitrate in the chloroplasts. GLN2 is a target for thioredoxin.
