一般說明
Membrane Preparations for Vesicular Transport Assays (VT) are suitable for general drug-efflux transporter interaction studies. Both substrate and inhibitor interactions can be assessed using vesicles. The success of substrate interaction studies strongly depends on the passive permeability of the compound. High permeability substrates might not be detected. Control Membranes with no-, or significantly lower transporter activity are also available.
應用
In the vesicular transport assay so-called "inside-out" membrane vesicles containing ABC transporters are applied. Incubating substrates of the respective efflux transporter in the presence of the inverted membrane vesicles and ATP will allow measuring accumulation of the substrates into the vesicles. In many cases radiolabeled reporter substrates are used but recently SOLVO developed the new PREDIVEZTM Vesicular Transport Kits that use fluorescent reporter substrates.
The standard vesicular transport assay is an inhibitory assay performed with cold test articles. This assay provides information on any interaction between the ABC transporter and the test article. The transport of the reporter substrate is measured in the presence of the test article (typically in 7 concentrations) and IC50 is defined as the concentration inhibiting the transport of the reporter substrate by 50%.
Should radiolabeled form of the investigated compound or adequate analytical methods (LC/MS, HPLC) be available, the vesicular transport assay may be performed in a direct format without the reporter substrate and may identify substrate nature of the test article. The vesicular transport substrate assay is a low throughput assay. It is suitable for low permeability test compounds as high permeability compounds may escape from the vesicles through the lipid bilayer.
PREDIVEZ vesicular transport kit is sold separately. This transporter membrane vesicle assay requires the PREDIVEZ vesicular transport kit and corresponding control membrane below:

Multidrug Resistance Proteins (MRPs), together with the cystic fibrosis conductance regulator (CFTR/ABCC7) and the sulfonylurea receptors (SUR1/ABCC8 and SUR2/ABCC9) comprise the 13 members of the human "C" branch of the ATP binding cassette (ABC) superfamily. All C branch proteins share

The multidrug resistance-associated protein (MRP) mediates the cellular excretion of many drugs, glutathione S-conjugates (GS-X) of lipophilic xenobiotics and endogenous cysteinyl leukotrienes. Increased MRP levels in tumor cells can cause multidrug resistance (MDR) by decreasing the intracellular drug concentration. The

Multidrug ABC transporters such as P-glycoprotein (P-gp/MDR1/ABCB1) and multidrug resistance protein 1 (MRP1/ABCC1) play an important role in the extrusion of drugs from the cell and their overexpression can be a cause of failure of anticancer and antimicrobial chemotherapy. Recently

The transport mechanism by which the multidrug resistance protein 1 (MRP1) effluxes cytotoxic agents out of cells is still not completely understood. However, the cellular antioxidant glutathione (GSH) has been shown to have an important role in MRP1-mediated drug transport.
