product information

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


KLH-conjugated synthetic peptide derived from N terminus of Raphanus sativus PAQ1O80368. Chosen peptide is conserved in PIP1;1, PIP1;2, PIP1;3 N-terminus.

Host Rabbit
Clonality Polyclonal
Purity Serum
Quantity 100 ĩl

store at -20°C; 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 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)

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.

Protocol for plant membrane isolation can be found here.

application example



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.
