Plant/Algal cell antibodies / Membrane transport system / Vacuolar membrane

product information

MRP1 (EC= 3.6.3.44) is a pump for glutathione S-conjugates.  Alternative names: ABC transporter ABCC.1, multidrug resistance-associated protein 1, glutathione S-conjugate-transporting ATPase 1, ATP-energized glutathione S-conjugate pump 1

KLH-conjugated synthetic peptide derived from Arabidopsis thaliana MRP1,Q9C8G9

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.

ELISA (ELISA), western blot (WB)

collection of antibodies to tonoplast proteins 

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 tonoplast membrane preparation is available here.

application information

1: 8000 (ELISA), 1: 2000 with standard ECL (WB)

181.9 |180 kDa (Arabidopsis thaliana)

Arabidopsis thaliana

dicots including: Vitis vinifera, monocots including: Oryza sativa, Triticum aestivum, trees: Populus balsamifera, moss: Physcomitrella patens

no confirmed exceptions from predicted reactivity known in the moment

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.

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-AtMTP4 antibodies (AS09 472, 1:1000, 1h) and secondary anti-rabbit (1:2000, 1 h). All steps were performed in RT with agitation.
