DEVELOPMENT OF A SIMPLE AND SENSITIVE ENZYME- LINKED IMMUNOSORBENT ASSAY (ELISA) FOR CLINICAL MEASUREMENT OF TESTOSTERONE USING PENICILLINASE AS LABEL
An enzyme-linked immunosorbent assay using a homologous combination of antiserum raised against testosterone-3-0-carboxymethyloxime-bovine serum albumin (T-3-0-CMO-BSA ) and penicillinase-labelled T-3-0-CMO was developed. This assay was utilized to measure testosterone in serum samples of male and female subjects. The sensitivity of the assay is 50pg/well and the antibody developed crossrea...
متن کاملTyping of hepatitis C virus isolates and characterization of new subtypes using a line probe assay.
A reverse-hybridization assay, the line probe assay (LiPA), based on variations found in the 5' untranslated regions of the different hepatitis C virus (HCV) genotypes was developed, permitting simple and fast determination of four HCV genotypes and their subtypes. Using this assay, 61 PCR-positive Brazilian HCV sera were typed. Of the sera, 33% had a type 1 HCV infection, 38% had type 1b (rela...
متن کاملComparison of three different HCV genotyping methods: core, NS5B sequence analysis and line probe assay.
To evaluate the capacity of Versant HCV genotype assay (LiPA) 2.0 to identify hepatitis C virus (HCV) genotypes, 110 serum samples were collected from chronic hepatitis C patients. Three methods were compared: core sequence analysis, NS5B sequence analysis and the INNO-LiPA assay. The result showed that 102 (92.7%) of the samples were amplified in either or both regions, of which 97 were amplif...
متن کاملENZYME-LINKED IMMUNOSORBENT ASSAY OF NEOPTERIN USING PENICILLINASE AS LABEL
An enzyme-linked immunosorbent assay for neopterin using penicillinase as marker enzyme is reported here by polyclonal antibodies against neopterin conjugated to bovine serum albumin which were raised in rabbits. Immunoglobulin fractions were purified and coated on wells of microtiter plates. A chain heterology was introduced in neopterin derivative and conjugated to penicillinase. The assa...
متن کاملEstablishment of NS3 tumor cell line expressing Hepatitis C virus Non-structural Protein 3 as valuable tool for HCV challenging in mice
Introduction: Hepatitis C virus (HCV) is one of the major medical problems. Human and chimpanzees are the only specific hosts which are naturally susceptible to HCV infection. Mice and other common laboratory animals are resistant to the virus, hence HCV prophylactic and therapeutic researches are very difficult and challenging. HCV non-structural protein 3 (NS3) is one of the most attractive t...
