Gold magnetic nanoparticle conjugate-based lateral flow assay for the detection of IgM class antibodies related to TORCH infections.

Development of a Lateral Flow Immunoassay Using Recombinant Dense Granular Antigen (GRA) 7 to Detect Anti-Toxoplasma gondii IgG Antibodies

Toxoplasma gondii is an intracellular protozoan parasite that causes toxoplasmosis and is of medical importance in pregnant women and immunosuppressed patients. In recent years, many methods have been developed for the detection of infection caused by this parasite; however, most of the developed methods are not adequately sensitive. The dense granular antigen (GRA) ...

Prevalence of serum antibodies to TORCH infection in the first trimester of the pregnancy in Kashan, Iran

Introduction:TORCH infections causing via Toxoplasma gondii, other microorganisms (e.g., Treponema pallidum), Rubella virus, Cytomegalovirus (CMV) and the Herpes Simplex Virus (HSV) types 1 and 2 during the first trimester of pregnancy can lead to severe fetal anomalies or even fetal loss. The current study determined the serological data of TORCH infections in women who were in their first tri...

ENHANCED PERFORMANCE OF A LATERAL FLOW ASSAY Use of a novel conjugate blocking technology to improve performance of a gold nanoparticle-based lateral flow assay

A dual gold nanoparticle conjugate-based lateral flow assay (LFA) method for the analysis of troponin I.

For signal amplification without an additional operation step in a gold nanoparticle (AuNP)-based lateral flow assay (LFA), a new and simple method utilizing two AuNP-antibody conjugates was developed. The 1st conjugate was the AuNP immobilized with an anti-troponin I antibody and blocked with bovine serum albumin (BSA), and the 2nd conjugate was the AuNP immobilized with an anti-BSA antibody a...

investigation of the prevalence of toxoplasma antibodies in women during marriage consultation in Kerman city

based on serological,toxoplasmosis infection is a widespread disease.with regard to this fact and because of the occurence of congenital toxoplasmosis infections due to asymptomatic infections in pregnant women,determination of the rate of toxoplasma antibodise(IgG,IgM) before pregnancy and finding the involved factors in increasing toxoplasmosis prevalence seems to be necessary.in this cross s...
