The cut-off values used in C6 peptide-based enzyme immunoassay (EIA), a widely test Lyme borreliosis (LB) serology, have not been thoroughly analysed. objective of the study was to examine performance EIA, and determine optimal for test. analysed data contained results 1368 serum samples. EIA index were compared statistically with immunoblot (IB) results. identified further tested well-defined ...

Recently we developed an enzyme immunoassay involving the use of steroid delta-isomerase (EC 5.3.3.1) as enzyme label and exclusion-affinity chromatography for rapid separation of free antigen-enzyme conjugate that bound to antibodies (J. Immunol. Methods 35: 267-284, 1980). Here we describe an automated version of this procedure, for immunoassay of progesterone and choriomammotropin (human pla...

background: rotavirus is a major cause of morbidity and mortality among children with gastroenteritis. since the discovery of rotaviruses, several techniques have been used for their laboratory diagnosis; those included electron microscopy (em) and enzyme immunoassay. these methods, however, are expensive and not readily available everywhere. we have developed a technique which can be used for ...
