Although the media and the public are worried about the infectious risks of transfusion, hemovigilance reports show that antigen-antibody reactions are responsible for the vast majority of acute ...

This antibody, which was of the IgG class, fixed complement, and its concentration decreased and then increased after one of the reactions. We postulate that an antigen–antibodycomplement ...

Antibodies, also known as immunoglobulins (IGs), are glycoproteins produced in response to an immune reaction and exhibit high specificity for the antigens that elicit the response. An antibody ...

and permeabilization or antigen retrieval treatments may be required to make the target or epitope accessible to the antibody. However, both fixation and permeabilization can affect immune affinity ...

Here, we discuss strategies to select the best therapeutic antigen targets, to optimize the structure of IgG antibodies and to design related or new structures with additional functions.

They don't yet know whether this chain reaction ... some of the antibodies were not binding directly to the HIV viral antigen, but to immune molecules on its surface. "These antibodies actually ...

which can trigger serious allergic reactions. Additionally, only a few of these antibodies specifically target the venom from the snake that caused the bite, requiring higher doses. Normally, cells ...

The apparatus, sequence of binding reactions and macroscopic signaling ... This second binding, with the coalescence of the antigen–antibody complexes, produces the appearance of a colored ...
