Application of fluorescein copolymer to improve the efficiency of counter-immunoelectrophoresis for diagnostics of animal infectious diseases [PDF]

The Ukrainian Biochemical Journal, 2021
The counter-immunoelectrophoresis (CIE) is a highly specific, simple and rapid method, which does not require expensive equipment, input materials and long-term staff training as compared with other express methods of viral infections diagnostic. Despite

NbX: Machine Learning-Guided Re-Ranking of Nanobody–Antigen Binding Poses

Pharmaceuticals, 2021
Modeling the binding pose of an antibody is a prerequisite to structure-based affinity maturation and design. Without knowing a reliable binding pose, the subsequent structural simulation is largely futile.

The COVID Complex: A Review of Platelet Activation and Immune Complexes in COVID-19

Frontiers in Immunology, 2022
Coronavirus disease 2019 (COVID-19) is a highly prothrombotic viral infection that primarily manifests as an acute respiratory syndrome. However, critically ill COVID-19 patients will often develop venous thromboembolism with associated increases in ...

Structural consensus among antibodies defines the antigen binding site. [PDF]

PLoS Computational Biology, 2012
The Complementarity Determining Regions (CDRs) of antibodies are assumed to account for the antigen recognition and binding and thus to contain also the antigen binding site.

Quantitative Description of Surface Complementarity of Antibody-Antigen Interfaces

Frontiers in Molecular Biosciences, 2021
Antibodies have the remarkable ability to recognise their cognate antigens with extraordinary affinity and specificity. Discerning the rules that define antibody-antigen recognition is a fundamental step in the rational design and engineering of ...

pH-Regulated Strategy and Mechanism of Antibody Orientation on Magnetic Beads for Improving Capture Performance of Staphylococcus Species

Foods, 2022
Immunomagnetic beads (IMBs) have been widely used to capture and isolate target pathogens from complex food samples. The orientation of the antibody immobilized on the surface of magnetic beads (MBs) is closely related to the effective recognition with ...

The biological activity of soluble antigen-antibody complexes: II. Physical properties of soluble complexes having skin-irritating activity [PDF]

, 1959
Previous work by Germuth and McKinnon (1), Trapani et al. (2), and ourselves (3) has established the fact that soluble antigen-antibody complexes formed in excess antigen can, (a) induce symptoms similar to anaphylaxis, (b) cause contraction of isolated ...
