product information

V-PPase (pyrophosphate-energized vacuolar membrane proton pump 1), EC=, acts to establish proton gradient of often higher magnitude than H+-ATPase. Is involved in auxin transport and NaCl and drought tolerance.  Alternative names: pyrophosphate-energized inorganic pyrophosphatase 1, H(+)-PPase 1, vacuolar proton pyrophosphatase 1, vacuolar proton pyrophosphatase 3

Secondary antibodies

Additional information Antibodies will detect target protein in 1 µg of a crude membrane preparation loaded per well. If purified preparations of vacuolar and plasma membranes are used, less than µg load per well should be sufficient.

Protocol of isolation of vacuolar membrane is available here. Please note that vacuolar membrane accounts for 10 % of protein of the total memrbanes of growing plant tissues. Recovery of vacuolar membrane following this protocol will depend upon amount of starting material used.

application example

western blot using anti-VPP-ase antibodies

Different amounts (depending of the tissue) of membrane proteins from developing xylem tissue of Norway spruce were separated in a gradient (4-15 %) SDS-PAGE gel and blotted 30 min to nitrocellulose membrane using a standard semi-dry Trans-Blot ® Turbo ™ (Bio-Rad) system. Blots were blocked with 5% non-fat milk protein for 1 h at room temperature (RT) with agitation. Blot was incubated in the primary antibody V-PPase (Agrisera) at a dilution of 1: 5 000 overnight with agitation. The antibody solution was decanted and the blot was rinsed briefly, and then washed 3 times for 15 min in TBS-T at RT with agitation. Blot was incubated in the secondary antibody (anti-rabbit IgG horseradish peroxidase conjugate, from Agrisera, AS09 602) diluted to 1: 10 000 for 1 h at RT with agitation. The blot was washed as above and the presence of V-PPase detected with ECL according to the manufacturer's instructions. Exposure time was ~ 1 second.
