product information
Background V-ATPase subunit VHA-a1 is a subunit of the membrane-integral Vo subunit. VHA-a1 target the V-ATPase enzyme to the trans-golgi network/earl endosome (TGN/EE) in Arabidopsis thaliana. This enzyme is involved in acidification process of various compartements of eucaryotic cells. The protein is coded by VHA-a1 gene AT2G28520. Alternative names: vacuolar H(+)-ATPase subunit a1, V-ATPase 93 kDa subunit.

KLH-conjugated synthetic peptide derived from Arabidopsis thaliana V-ATPase subunit A, O23654, At1g78900

Host Rabbit
Clonality Polyclonal
Purity Affinity purified serum in PBS, pH 7.4
Format Lyophilized
Quantity 100 µg

aplication example

western blot using anti-VHa1 antibodies

10 μg of microsomal membranes were isolated from 6-days-old etiolated (dark-grown) Arabidopsis thaliana seedlings with Extraction buffer (450mM sucrose, 50mM HEPES pH7.5, 5mM MgCl2, 1mM DTT, 1x protease inhibitor). Proteins were denaturated in SDS sample buffer for 5 min at 95°C. Proteins were separated on a 10% SDS-PAGE and blotted 1h to a nitrocellulose membrane using tank transfer. Blots were blocked with 4% dry milk in TBS-T for 2h at room temperature (RT) with agitation. Blot was incubated in the primary antibody (#AS14 2822) at a dilution of 1:1000 in blocking buffer for 16h with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, then washed 3 times for 15 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 1:25 000 in blocking buffer for 2h at RT with agitation. The blot was washed as above and developed for 3 min with ECL according to the manufacturer's instructions peqlab AceGlow Kit & INTAS digital imager. Exposure time was 3 min.
