  1. The results from this assay are provided to the customer in the ExpressPlus report format, which may include graphical representations of data and comparison with historical data for reference compounds.
  2. The solubility of the test compound in Hanks’ buffer containing < 0.8% DMSO must be greater than the test concentration. If the solubility of the test compound is unavailable, Absorption Systems can conduct a solubility assessment at an additional charge.
  3. Percent inhibition is calculated as 100 x [1-(IROAT3-IRVC)TC / (IROAT3 - IRVC)0], where IROAT3 is the influx rate of furosemide in OAT3-transfected cells, IRVCis the influx rate in vector control cells, “TC”  means in the presence of test compound, and “0” means in the absence of test compound.
