Measurement of chemiluminescence (CL) may be used in immunological researches for functional study of polymorphonuclear cells (PMNs) and luminescent immunoassay.PMNs may be activated by various stimulants such as opsonized zymosan

immune complexes (IC)

PMNs-combining antibody etc. with oxidative metabolic enhancement which may be measured by luminometer. The functions of PMNs are expressed with the CL peak and the peak time arrived. Measurement of CL will be used in the diagnosis of PMNs diseases

in the immunopathological and basic immunological researches.Luminescent immunoassay (LIA) has been established recently. The principles of LIA are same as RIA or EIA

but luminol

iscluminol or peroxidase are used as labelling substances. Due to the characteristics of rapidity

sensitivity and specificity of the reacticns

LIA will be tsed broadly in many aspects of imnunological researches.
