Epitope-specific antibody response to IgE by mimotope immunization.
We have previously described a mouse monoclonal anti-human IgE antibody (BSW17) capable of recognizing receptor-bound IgE without inducing mediator release from human basophils or mast cells. Moreover, immune complexes of IgE and BSW17 are not able to bind to the IgE receptor. An initial attempt to map the precise epitope recognized by this mAb by using Fc epsilon-derived peptides of variable l...
متن کاملImmunization of Sheep with Phage Mimotopes against Dermatophilosis
Random peptide libraries (RPL) displayed on the surface of filamentous bacteriophages have been extensively used as a tool to map epitopes or to identify antigenic mimics (mimotpoes) of disease-specific monoclonal antibodies or polyclonal sera. These RPL are engineered by the insertion of degenerate oligonucleotides, encoding a specific number of random amino acids, in frame with a bacteriophag...
متن کاملInduction of high titers of anti-IgE by immunization of inbred mice with syngeneic IgE.
We have generated high titers (up to 1 mg/ml) of antibodies to isotypic determinants of IgE by immunization of A/J mice with syngeneic monoclonal IgE conjugated to keyhole limpet hemocyanin. As much as 3 mg of anti-idiotypic antibodies per ml was induced at the same time. In contrast to conventional rheumatoid factors, the anti-isotypic antibodies are of moderately high affinity (10(7)-10(8) M-...
متن کاملDirect immunoprecipitation of antigen with phage displaying immunoglobulin fragment.
Phage libraries may display hormones, receptors, antibody fragments, etc., by fusion to phage envelope proteins. This report describes the direct precipitation of phage-Fab-antigen complexes by polyethylene glycol precipitation, resulting in highly selective and efficient recovery of antigen from complex mixtures without nonspecific protein contamination. The method demonstrates efficiency and ...
متن کاملPeptide-displaying phage technology in glycobiology.
Phage display technology is an emerging drug discovery tool. Using that approach, short peptides that mimic part of a carbohydrate's conformation are selected by screening a peptide-displaying phage library with anti-carbohydrate antibodies. Chemically synthesized peptides with an identified sequence have been used as an alternative ligand to carbohydrate-binding proteins. These peptides repres...
