The AquaLite® Prolactin Bioluminescent Immunoassay (BIA) Kit (or the AquaLite® Prolactin assay) is intended to be used in clinical laboratories for the quantitative determination of human prolactin levels in sera and plasma. The AquaLite® Prolactin assay is for in vitro diagnostic use.

The AquaLite® Prolactin Bioluminescent Immunoassay Kit uses a mixture of mouse monoclonal and rabbit polyclonal with anti-prolactin activity that is pre-coated onto polystyrene tubes (solid phase). Samples (serum or plasma), or appropriate calibrators or controls, are pipetted (25 uL) into the pre-coated tubes. Anti-prolactin conjugate consisting of mouse monoclonal antibody covalently linked to AquaLite® (150µL) is then added to the tubes. The conjugate uses the photoprotein, AquaLite® (recombinant aequorin: U.S. Patent Nos. 5,422,266 and 5,486,455) which is covalently linked to an anti-prolactin polyclonal antibody. Prolactin in the sample simultaneously combines with polyclonal antibody on the solid phase and conjugate antibody to form an immune complex or "sandwich" bound to the solid phase. Complex formation is complete after a 60-minute incubation period at room temperature (18° to 25°C) on a standard orbital shaker. The tubes are then washed to remove unbound conjugate.

The washed tubes are placed in a luminometer that is capable of reading a triggered. flash-type reaction in 12 x 75 mm tubes. An injected calcium trigger solution causes AquaLite® to oxide its self-contained luciferin molecule. This reaction produces a twosecond flash of light at 469 nm, which is measured by the luminometer. The intensity of the light is directly proportional to the concentration of the prolactin in the sample. To calculate results, the luminometer uses a cubic spline curve fit applied to a logit-log transformation of the light intensity (in relative light units, RLU) of the prolactin calibrators versus prolactin concentration (in ng/mL).

Note: Samples that generate signals greater than the signal from the highest calibrator are off-scale. These samples must be diluted and re-assayed. Remember to multiply the results from diluted samples by the dilution factor used.
