Isolated five known iridoids glycosides (Scrophuloside A, Harpagoside B, 5-hydroxyloganin, 8-O-acetylharpagide and 6-O-methyl,1-glucopyranosyl catalpol ),one phenyl ethanoid glycoside (Verbascoside) and a phenyl ethanol amine (2-(4-Chlorobenzyl amino) ethanol ) compound from the methanolic extract of aerial parts of Scrophularia oxysepala using by high performance liquid chromatography based on...

a dot immunobinding assay ( dia) was used for a quantitative and qualitative assay of rubella antibody. purified antigen and conjugated anti-human immunoglobulin (rahlg) were prepared. nitrocellulose paper dotted with the antigen was added to serially diluted sera or blood samples. the reacting antibodies were visualized by a peroxidase system. development of a colored insoluble substrate was t...

BACKGROUND In evaluating a photochemical treatment process for inactivating parvovirus B19, there lacked simple culture methods to measure infectivity. The recently developed enzyme-linked immunospot (ELISpot) infectivity assay uses late-stage erythropoietic progenitor cells and is labor intensive and time consuming. We evaluated a novel, efficient polymerase chain reaction (PCR) inhibition ass...

We demonstrate the development of a multiplex droplet digital PCR assay for human cytomegalovirus (CMV), human adenovirus species F, and an internal plasmid control that may be useful for PCR inhibition-prone clinical samples. This assay performs better on inhibition-prone stool samples than a quantitative PCR assay for CMV and is the first published clinical virology droplet digital PCR assay ...
