Method Description
The patient sample is added to a solid phase that is coated with a mouse monoclonal antibody specific for prostatic acid phosphatase (PAP). A goat-anti-PAP-alkaline phosphatase conjugate is added to form an antibody sandwich complex. Excess conjugate is removed by washing, and an adamantyl dioxetane phosphate substrate is added to produce chemiluminescence. Light emission is proportional to PAP concentration in the specimen.(Package insert: IMMULITE 2000 PAP. PIL2KPA-17. Siemens Healthcare; 03/15/2018)
