Screening for anti(+)METH IgG response was conducted by radioimmunoassay (RIA)<ref name="Using hapten design to discover therapeutic monoclonal antibodies for treating methamphetamine abuse"/> in which radio labelled [(+)-3H] METH is competing with unlabelled (+)-METH and (+)-AMP for the binding site of Abs in a manner similar to what has been previously described<ref name ="Antibodies against arylcyclohexylamines and their similarities in binding specificity with the phencyclidine receptor"/>. An IC50 value was determined for each compound after fitting a sigmoidal curve to the data points<ref name="Pharmacodynamic mechanisms of monoclonal antibody-based antagonism of (+)-methamphetamine in rats"/><ref name="Using hapten design to discover therapeutic monoclonal antibodies for treating methamphetamine abuse"/>. | Screening for anti(+)METH IgG response was conducted by radioimmunoassay (RIA)<ref name="Using hapten design to discover therapeutic monoclonal antibodies for treating methamphetamine abuse"/> in which radio labelled [(+)-3H] METH is competing with unlabelled (+)-METH and (+)-AMP for the binding site of Abs in a manner similar to what has been previously described<ref name ="Antibodies against arylcyclohexylamines and their similarities in binding specificity with the phencyclidine receptor"/>.

Anti-(+)METH mAb6H4 was reported with Kd = 11 nM<ref name="Pharmacodynamic mechanisms of monoclonal antibody-based antagonism of (+)-methamphetamine in rats/>, having <.01% cross-reactivity with almost all compounds tested (including (-)-METH, (+/-)-AMP,(+/-)-MDMA,4-OH METH, Pseudoephedrine, Ephedrine, Dopamine, Norepinephrine, Serotonin, Epinephrine)<ref name="Pharmacodynamic mechanisms of monoclonal antibody-based antagonism of (+)-methamphetamine in rats/> except for (+)-methylenedioxymethamphetamine (MDMA) which has just slightly higher relative affinity than METH (9 nM to 11nM)<ref name="Pharmacodynamic mechanisms of monoclonal antibody-based antagonism of (+)-methamphetamine in rats/>. It was also stereospecific, having an approximately 100 times higher relative affinity for the plus form than the minus forms of these substances. | Anti-(+)METH mAb6H4 was reported with Kd = 11 nM<ref name="Pharmacodynamic mechanisms of monoclonal antibody-based antagonism of (+)-methamphetamine in rats"/>, having <.01% cross-reactivity with almost all compounds tested (including (-)-METH, (+/-)-AMP,(+/-)-MDMA,4-OH METH, Pseudoephedrine, Ephedrine, Dopamine, Norepinephrine, Serotonin, Epinephrine)<ref name="Pharmacodynamic mechanisms of monoclonal antibody-based antagonism of (+)-methamphetamine in rats"/> except for (+)-methylenedioxymethamphetamine (MDMA) which has just slightly higher relative affinity than METH (9 nM to 11nM)<ref name="Pharmacodynamic mechanisms of monoclonal antibody-based antagonism of (+)-methamphetamine in rats"/>.
