Host Rabbit

Clonality Polyclonal

Purity Serum

Format Lyophilized

Quantity 100 µl

Reconstitution For reconstitution add 100 µl of sterile water.

Storage Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.For long time storage over 1 year please dilute the antibody solution 10 fold with 10 mM Tris-buffered saline containing 10% glycerol. Glycerol may suppress denaturation of protein.

Tested applications ELISA (ELISA), Western blot (WB)

Recommended dilution 1 : 8000 (ELISA), 1 : 1000 (WB)

Application examples

Application example

western blot using anti-PIP1s antibodies

1 µg and 10 µg of crude membrane fraction/lane from Arabidopsis thaliana were separated on 12 % SDS-PAGE and blotted 1h to PVDF membrane (40 min. at 10 V using BioRad semidry transfer). Filters were blocked 1h with 5 % low-fat milk powder in TBS-T (0.05% Triton X.100). Membranes were washed 5 times with TBS-T, each time in a fresh polystyrene box and probed with anti-PIP1s ntibodies (diluted in 1: 500 (left panel) and 1: 1000 (right panel), AS09 489, and secondary anti-rabbit (1:2000, 1 h). All steps were performed in RT with agitation.

Additional information

0.1 % sodium azide is added as preservative. For antibody re-suspending information check the tube lable.

Antibodies will detect target protein in a few µg of a crude preparation loaded per well. If purified preparations of vacuolar and plasma membranes are used, one µg load per well should be sufficient.

Protein or membrane sample should be treated at 70°C for 10 min before loading on the gel.

Diluted antibody solution can be used 2 to 3 times within one month if it contains 0.1 % sodium azide as preservative and is stored at -20ºC to -80ºC.

Antibody reacts also with PIP2 isoforms in Zea mays.

Background

PIPs proteins are aquaporins which facilitate the transport of water and small neutral molecules across cell membrane. PIP1;2 is also designated as PIP1B.
