Since the epitope binding sites are located on the light chains, smaller but still specific probes can be generated by enzymatically snipping off the heavy chains, leaving 2 smaller molecules, referred to as …

WebMethods for functionally mapping epitopes often use binding assays such as western blot, dot blot, and/or ELISA to determine antibody binding. [18] Competition methods look to … WebThe strength of interaction between antibody and antigen at single antigenic sites can be described by the affinity of the antibody for the antigen. Within each antigenic site, the variable region of the antibody “arm” interacts through weak noncovalent forces with antigen at numerous sites. The greater the interaction, the stronger the ...

WebEpitope Selection Strategy: A typical peptide sequence of 15 amino acids in length will contain several epitope possibilities (5-7aa) against which individual antibodies will be generated. Ideally, this peptide sequence will correspond to a region of the protein that is exposed and accessible when the protein is folded into its native conformation. WebEpitope tag antibodies can be used for a variety of applications including protein purification, western blot, immunoprecipitation, flow cytometry, and immunofluorescence. …

WebProtease-induced Epitope Retrieval (PIER) In the PIER method, enzymes including Proteinase K, Trypsin, and Pepsin have been used successfully to restore the binding of an antibody to its epitope. The mechanism of action is thought to be the cleavage of peptides that may be masking the epitope.
