ABC Transporter and Assay

ABC Transporters

The ATP-Binding Cassette (ABC) transporters are a  family of membrane proteins, members of which are found in various living organisms from microbes to humans.  These transporters have ATPase activity and carry many drugs, fats, sterols and other endogenous metabolites. Forty-seven kinds of ABC transporter have already been identified in the human genome, and approximately 11 kinds are recognized as important drug transporters that transfer materials from the inside of cells to the outside.

ABC transporters may influence the absorption, distribution, metabolism, and excretion (ADME) properties, as well as the efficacy and toxicity of candidate drugs.  It is, therefore, important to examine the interaction of candidate drugs with these transporters to help identify drugs with high efficacy and low adverse effects.

ATPase Assay

ABC transporter activity is driven by the energy derived from hydrolysis of ATP.
The ATPase activity increases when a substrate interacts with an ABC transporter. The activity can be estimated by determining the concentration of inorganic phosphate resulting from ATP hydrolysis (ATPase assay). It is possible, therefore,to evaluate the interaction of a drug with an ABC transporter by means of ATPase assay without the need for radioisotope labeling of substrates.

Thus, ATPase assay can be employed as a convenient in vitro screening tool for ABC transporter substrates.


How should I prepare buffer for Vesicular Transport assay and ATPase assay?

We provide “Buffer Preparation Protocol” on our web-site. You can find the composition of buffer and preparative procedure in our protocol.

For Vesicular Transport assay, we also have launched three types of Reagent Set for your convenience. By purchasing these Reagent Sets, you do not need copmplicated reagent preparation.

What is the storage condition for ABC Transporter Membranes/Vesicles products?

Please sore them at a temperature of -80 degrees C.
