We have developed a sensitive method for the detection of recombinant antibody-antigen interactions in a microarray format. The biochip sensor platform used in this study is based on an oriented streptavidin monolayer that provides a biological interface with well-defined surface architecture that dramatically reduces nonspecific binding interactions. All the antibody or antigen probes were bio...

The detection of an antibody against nucleoprotein (NP) of the avian influenza virus (AIV) was attempted by an electrochemical immunoassay by combining a secondary antibody-alkaline phosphatase conjugate and 4-aminophenylphosphate. Released 4-aminophenol was quantitated electrochemically, and the current derived from oxidation of the hydrolysis product increased linearly over a wide primary ant...

Antibodies are a diverse class of glycoproteins that specially bind with antigen and elicit a number of secondary responses in vivo. Most of the applications of antibodies in basic research diagnosis and immunotherapy rely on labeling of the antibody with radiopharmaceuticals. Radiolabeled antibodies are a new class of imaging agents for the detection of sites of disease. True biodistribu...

Anti-N-Methyl-D-Aspartate-Receptor (NMDA-R) encephalitis is a new autoimmune disorder, often paraneoplastic in nature, presenting with complex neuropsychiatric symptoms. Diagnosed serologically, this disorder is often responsive to immunosuppressant treatment. We here in report the case of a 56-year-old man with anti NMDA-R encephalitis presenting initially with disorientation and hallucinati...

One of the most used ancillary techniques by surgical pathologists in clinical practice is immunohistochemistry (IHC) that, through an antibody–antigen reaction, allows for detection specific proteins at cellular level [...]

  Introduction: Development of effective immunodiagnostic methods for detection of Mycobacterium tuberculosis infection is crucial. Serodiagnostic methods, based on antibody response to specific antigens could provide promising approaches for rapid, economical and easy to perform diagnostic tests which are crucial for tuberculosis (TB) control. In this study, the level of IgG antibody responses...

experimental infection of muscovy ducks with v4 strain of newcastle disease virus was undertaken to determine the response of the ducks to the virus and the possibility of virus transmission to ducks and chickens in village like conditions. twelve ducks were randomly and equally divided into three groups of control, inoculated and in-contact. additionally, the chickens were placed into two grou...

Real-time PCR is a very sensitive technique to measure DNA concentrations. In real-time immuno-PCR, it is used as the detection system for quantification of proteins. Many ways to perform and assemble real-time immuno-PCR are possible. We have tested three different approaches for the detection of prostate specific antigen (PSA) and compared them with each other and with ELISA. We also demonstr...

In this study a label-free electrochemical Immunosensor for ultrasensitive detection of Hepatitis C virus core antigen in serum samples was fabricated by using a simple approach. In this method a low-cost and sensitive immunosensor was fabricated based on a boehmite nanoparticles (BNPs) modified glassy carbon. The BNPs provide a specific platform with increased surface area which is capable of ...
