  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-(IROCT1-IRVC)TC / (IROCT1 - IRVC)0], where IROCT1 is the influx rate of MPP+ in OCT1-transfected cells, IRVC is the influx rate in vector control cells, “TC”  means in the presence of test compound, and “0” means in the absence of test compound.
