The measurement of circulating hormones by immunoassay remains a cornerstone in preclinical endocrine research. For scientists conducting and interpreting immunoassay measurements of rodent samples, the paramount aim usually is to obtain reliable and meaningful measurement data in order to draw conclusions on biological processes. However, the biological variability between samples is not the o...

An indirect competitive fluorescence immunoassay using a DNA/dye conjugate as antibody multiple labels was developed on 96-well plates for the identification and quantification of 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) in aqueous samples. A hapten, 2,4,2'-tribromodiphenyl ether-4'-aldehyde, was synthesized, and was conjugated to bovine serum albumin to form a coating antigen. Specific reco...

Measuring bone turnover markers could detect early stages of osteoporosis and early responses to anti-osteoporotic treatments. Currently, commonly used bone turnover markers, N-telopeptides (NTx) and C-telopeptides (CTx), are measured using ELISA tests, which demands time and increases cost. Bone turnover markers need to be measured more easily for general use. Lateral flow-based immunoassay wo...

background helicobacter pylori (h. pylori) infection is common among humans and plays a major role in the etiology of peptic ulcer disease with significant morbidity in patients with hiv-1 on antiretroviral therapy. there are conflicting prevalence patterns of h. pylori in hiv-1 infected patients using various methods of detection. the noninvasive technique used for detection of h. pylori infec...
