An enzyme immunoassay was developed for the detection of human immunoglobulin M (IgM) antibody to different flavivirus antigens. The IgM antibody of human sera was selectively bound to anti-IgM antibody-coated solid-phase plates. Flavivirus IgM antibodies were then detected by use of various enzyme-labeled antigens. The flavivirus antigens (dengue type 2 virus, West Nile virus, and tick-borne e...

To the Editor: Bioavailable testosterone is often derived from the free androgen index (1), which is reliant on measurements of both testosterone and sex hormone-binding globulin (SHBG). Although testosterone assays are widely available in various formats, assays for SHBG are more restricted partly because of the absence of automated procedures and the relatively high expense of kits. Dako (Den...

Antibody was localized by electron microscopy within differentiating and mature plasma cells of the spleens of hyperimmunized rabbits. Horseradish peroxidase was used as antigen. Intracellular antibody to peroxidase was revealed in glutaraldehyde-fixed tissue by coupling it with its antigen and then revealing the sites of peroxidase activity cytochemically. Antibody first appears in the perinuc...

introduction: leukocytes causing a wide variety of side effects after transfusion are present in all blood products prepared by standard methods. as a consequence, the use of filter technology for leukoreduction has been widely practiced .according to aabb accreditation in 1996, leukoreduced blood components must contain less than 5×106 leukocytes per unit, but sometimes this value is higher ev...

background: immunopathological and inflammatory processes play important roles in the initiation and development of ischemic heart disease (ihd). objective: the aim of this study was to evaluate the serum levels of several autoantibodies including rheumatoid factor (rf), anti-nuclear antibodies (ana), anti-small nuclear ribonucleoprotein (anti-sm), anti-phosphatidylserine (anti-ps) and anti-car...

background: auto antibodies to zona-pellucida (aza) seem to be important autoantibodies implicated in reproduction, with substantial role in both endocrine and reproductive functions of the human ovary. there are some debates on the relation of aza with infertility, repeated in vitro fertilization (ivf) attempts, and outcome of it. objective: in this study, we assessed the presence of aza in th...

A biotin-tyramine conjugate (1) was found to covalently cross-link with peroxidase antibody 7G12 upon the catalytic oxidation of the tyramine moiety in the presence of hydrogen peroxide (H2O2). On the basis of this observation, a novel strategy was developed to select mutants of 7G12 Fab with enhanced peroxidase activity from a library of phage displayed antibodies. In such a selection, tyramin...

A direct enzyme-linked immunosorbent assay (ELISA) is described that uses horseradish peroxidase-labeled antigen for detection of immunoglobulin M (IgM) and IgA antibodies to toxoplasma. In this assay, polystyrene microtiter plates were sensitized with anti-human IgM or IgA antibody to separate IgM or IgA from other classes of antibody. The presence of IgM or IgA antibodies to toxoplasma (Tox-I...
