The rotavirus nonstructural protein 4 (NSP4), is a multi functional protein that play key role in both viral morphogenesis and cytopathic effect associated with cell death. However, the complete biological effect of NSP4 remains to be clarified. Since to obtain further knowledge about this protein there is a need for recognizing antibody and there is no commercial antibody against this protein,...

ricin, the toxic lectin extracted from the castor bean plant (ricinus communis), consists of an a chain (rta) and a b chain (rtb). anti-a chain abs and anti-b chain abs can neutralize toxins in vivo and in vitro via blocking the binding of the toxin to the cell. also, rtb protein is able to serve as an antigen deliver to the mucosal immune system and act as an immunoadjuant. here, the genomic d...

Although antibody functions are executed in heterogeneous blood streams characterized by molecular crowding and promiscuous intermolecular interaction, detailed structural characterizations of antibody interactions have thus far been performed under homogeneous in vitro conditions. NMR spectroscopy potentially has the ability to study protein structures in heterogeneous environments, assuming t...

Humans develop polyclonal, serotype-specific neutralizing antibody responses after dengue virus (DENV) infection. Many mouse antibodies that neutralize DENV bind to the lateral ridge or A strand epitopes on domain III of the viral envelope (EDIII) protein. It has been assumed that these epitopes are also the main target of human neutralizing antibodies. Using recombinant dengue serotype 2 virus...

Two monoclonal antibodies CH6 and C1E3 were used in an antibody class capture assay for the detection of IgM antibodies specific for Toxoplasma gondii. CH6 was used on the solid phase to capture human IgM. After a Toxoplasma gondii antigen had been added, specifically bound material was detected using C1E3 coupled to horseradish peroxidase. The assay was compared with an established system usin...
