Isolation of Anti-Ricin Protective Antibodies Exhibiting High Affinity from Immunized Non-Human Primates
Ricin, derived from the castor bean plant Ricinus communis, is one of the most potent and lethal toxins known, against which there is no available antidote. To date, the use of neutralizing antibodies is the most promising post-exposure treatment for ricin intoxication. The aim of this study was to isolate high affinity anti-ricin antibodies that possess potent toxin-neutralization capabilities...
متن کاملHigh avidity IFN-neutralizing antibodies in pharmaceutically prepared human IgG.
This paper demonstrates and characterizes naturally occurring antibodies to interferon (IFN) in human IgG preparations. In vitro neutralization of the antiviral effect of IFN alpha and IFN beta, but not IFN gamma, was observed in 12 of 15 normal IgG preparations. The neutralizing capacity was higher against rIFN alpha 2A and rIFN alpha 2C than against lymphoblastoid IFN alpha and IFN beta. Früh...
متن کاملLack of Protection following Passive Transfer of Polyclonal Highly Functional Low-Dose Non-Neutralizing Antibodies
Recent immune correlates analysis from the RV144 vaccine trial has renewed interest in the role of non-neutralizing antibodies in mediating protection from infection. While neutralizing antibodies have proven difficult to induce through vaccination, extra-neutralizing antibodies, such as those that mediate antibody-dependent cellular cytotoxicity (ADCC), are associated with long-term control of...
متن کاملEarly high-affinity neutralizing anti-viral IgG responses without further overall improvements of affinity.
Affinity maturation of IgG antibodies in adaptive immune responses is a well-accepted mechanism to improve effector functions of IgG within 2 weeks to several months of antigen encounter. This concept has been defined mainly for IgG responses against chemically defined haptens. We have evaluated this concept in a viral system and analyzed neutralizing IgG antibody responses against vesicular st...
متن کاملMeasurement of Affinity Constant of Anti-human IgG Monoclonal Antibodies by an ELISA-based Method
Background: The affinity of an antibody to its antigen is a crucial parameter in its biological activity and performance of an immunoassay such as ELISA. Affinity of most IgG specific MAbs are often determined by methods which require labeling of either antigen or antibody, and are sometimes difficult to control, do not always lead to the expected signal and often result in immunological modifi...
