AS07 213P | Blocking peptide

product information

background

Plant vacuole V-ATPase is responsible for energization of transport of ions and metabolites, and acts as well 'house-keeping' and as a stress response enzyme. V-ATPase is a multi-subunit enzyme composed of a membrane sector and a cytosolic catalytic sector. It is related to the FoF1 ATP synthase. Alternative protein names: Vacuolar proton pump subunit E, Protein EMBRYO DEFECTIVE 2448

immunogen

KLH-conjugated synthetic peptide chosen from subunit E of plant V-ATPase including Arabidopsis thaliana At4g11150. Peptide is conserved in vacuolar H+-ATPase subunit E, isoform 1 to 3 (VHA-E1).

application example

10 µg of total leaf protein extracted with PEB (AS08 300) from (1) Arabidopsis thaliana, (3) Zea mays, and (4) Hordeum vulgare together with (2) cytosolic extract from Arabidopsis thaliana leafs were separated on 4-12% NuPage (Invitrogen) LDS-PAGE and blotted 80 min (30V) to nitrocellulose. Filter was blocked 1h with 2% low-fat milk powder in TBS-T (0.1% TWEEN 20) and probed with anti-V-ATPase (AS07 213, 1:2000, 1h) and secondary anti-rabbit (1:40000, 1h) antibody (HRP conjugated, recommended secondary antibody AS09 602) in TBS-T containing 2% low fat milk powder. Antibody incubations were followed by washings in TBS-T (15, +5, +5, +5 min). All steps were performed at RT with agitation. Signal was detected with SuperSignal West Pico (Thermo Scientific) using a GenoPlex Chemi CCD (accumulated signal 10 x 30s exposure, bin 2x2).

application example

Standard IF protocol for plant material has been used including slight fixation with formaldehyde followed by washing and incubation with primary and secondary antibodies conjugated to fluorescent dyes.
