Manuka honey is known as one of the premium honeys because of its unique property: a potent antibacterial activity. Leptosperin, methyl syringate 4-O-β-d-gentiobioside, has been specifically identified in manuka honey. Because leptosperin is relatively stable under warmer conditions, measuring leptosperin levels may be applied to authenticate manuka honey. In this study, an immunochromatographi...
Serodiagnosis of plague is very useful for its retrospective confirmation and for epidemiologic studies in humans and in rodents, since rats constitute the main natural reservoir of Yersinia pestis. We have developed a rapid test for the detection of IgG antibodies to fraction 1 (F1) based on immunochromatography and protein A to detect both human and rat IgG. When tested with reference human s...
BACKGROUND Schistosomiasis remains a major public health concern in China and an epidemiological survey has revealed that schistosome-infected bovines and goats are the main transmission sources for the disease. Therefore, development of a sensitive technique for the diagnosis of schistosomiasis in domestic animals is necessary. METHOD A novel colloidal gold immunochromatography assay (GICA) ...
OBJECTIVE Organophosphorus (OP) pesticides are considered hazardous substances because of their high toxicity to nontarget species and their persistence in the environment and agricultural products. Therefore, it is important to develop a rapid, sensitive, and economical method for detecting OP pesticides and their residues in food and the environment. METHODS A broad, selective monoclonal an...
During the 2016-17 winter season in Japan, human norovirus GII.P16-GII.2 strains (2016 strains) caused large outbreaks of acute gastroenteritis. Phylogenetic analyses suggested that the 2016 strains derived from the GII.2 strains detected during 2010-12. Immunochromatography between 2016 strains and the pre-2016 GII.2 strains showed similar reactivity.
A simplified lateral-flow assay for the detection of antibodies to HIV using magnetic-bead conjugates and multibranched peptides from both HIV-1 and HIV-2 was developed. Magnetic immunochromatography testing (MICT) uses a standard lateral-flow platform that incorporates magnetic-bead conjugates for quantitative measurement of the magnetic field distortion associated with the bound magnetic conj...
We describe the development and performance of a second-generation enzyme immunochromatography method for visually quantifying theophylline in whole blood without the use of instrumentation. We have developed the novel concept of an internal chemical clock reaction to combine the capillary-migration and color-generation protocol of the two-step immunochromatographic assay into a single-step, si...
