Cocaine Metabolite ELISA Kit

Storage Instruction:Store the kit at 4°C.
Description:
The Cocaine Metabolite ELISA Kit is a single incubation assay providing results similar to those obtained by existing methods . Native (unaltered) cocaine urine concentration is far lower than that of its major metabolite benzoylecgonine. After intra- venous administration of l00mg cocaine urine concentrations ranged from 1.2 - 2.4 ug/ml compared with concentrations ranging from 5 - 55 ug/ml for benzoylecgonine . Cocaine was undetectable (at a 50 ng/ml cut-off) 12 hours after administration in comparison with benzoylecgonine which persists hours to days after administration . It has been suggested that a benzoylecgonine/cocaine ratio of less than 100 is indicative of use within the past 10 hours.
