IMMULITE® 1000 Chemiluminescent Technology
The heart of IMMULITE 1000 is the proprietary Test Unit, which offers a breakthrough in automated bead washing. The Test Unit, containing an assay-specific 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 1000's unique wash technique produces extremely low and consistent nonspecific binding, which is critical for assay performance.
IMMULITE 1000'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 1000 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.
