WebHPAC is based on immobilisation of a protein target on a stationary phase, which selectively retains drugs, typically HSA or AAG, since these are the main proteins that bind drugs. This is consistent with typical reverse phase chromatography methodology where the test molecule passes through the column in the mobile phase. WebSince the stationary phase is hydrophilic in this technique, molecules with hydrophilic properties contained within the mobile phase will have a high affinity for the stationary phase, and therefore will adsorb to the column packing.
