      Proprietary Wash Technique

      The heart of IMMULITE® is the proprietary Test Unit, which offers a breakthrough in automated bead washing. The Test Unit, containing an assay-specific antibody-coated bead, serves as the reaction vessel for all sample processing. Spinning the Test Unit at high speed efficiently expels fluid into the integral sump chamber. The tube design allows for multiple discrete washes within seconds, ensuring excellent separation of unbound material for highly sensitive assays. IMMULITE’s unique wash technique produces extremely low and consistent nonspecific binding, which is critical for assay performance.

      Sample and reagent are automatically pipetted into the Test Unit, which is then incubated at 37°C with intermittent agitation.

      Following incubation, the Test Unit is spun at high speed about its vertical axis. Reaction fluid is forced up and completely captured in the sump chamber.

      A series of washes efficiently removes unbound material from the bead and inner tube.

      Chemilumin-escent substrate is added to the Test Unit. Light emission is read with a high sensitivity photon counter.

      Sustained Chemiluminescence

      IMMULITE’s enzyme-amplified chemiluminescence translates into lower detection limits compared to conventional “flash” chemiluminescence. Rather than one or two photons per immuno-binding event, thousands of photons are emitted per binding event with the IMMULITE reaction. Automatic light signal attenuation effectively broadens the range of luminometer readings 100-fold. The sustained signal produced by the enzyme-enhanced chemistry allows multiple readings to be taken for more precise measurements.
