The discovery of immunoglobulin E.

The video demonstrates a paper-based immunoassay, involving amine-functionalized cellulose discs cross-linked with glutaraldehyde. Covalent immobilization of IgG-Fc-specific capture antibodies, followed by the introduction of immunoglobulin G and horseradish peroxidase-conjugated detection antibodies, results in a color change confirming the presence of immunoglobulin...

Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

This video demonstrates a method for assessing the antibody immune response to a novel nanoemulsion adjuvant vaccine in pre-immunized mice. Immunization enhances antibody response as confirmed by determining the IgG antibody...

This video demonstrates a protocol for detecting serum-specific immunoglobulin E using a microfluidic cartridge-based chemiluminescence system. Serum IgEs interact with distinct allergens immobilized in the reaction zone of the cartridge, which are subsequently detected with peroxidase-conjugated anti-IgE antibodies and a chemiluminescent substrate, allowing simultaneous detection of multiple allergen-specific...

The video demonstrates a cell-based assay for detecting anti-aquaporin-4 immunoglobulin G using a biochip containing untransfected cells and transfected cells expressing aquaporin-4. This method has applications in diagnosing neuromyelitis optica spectrum disorders, confirmed by strong green fluorescence on the...
