Epitope Mapping by Region-Specified PCR Mutagenesis
互联网
478
This technique was developed for mapping of epitopes of monoclonal antibodies (MAb) at the amino acid sequence level; i.e., the identification of amino acids of an antigenic protein involved in specific interactions with each antibody. The epitope mapping includes:
| 1. |
Construction of a random base substitution DNA library for the gene encoding the antigenic protein in the λ-gt11 phage expression-vector;
|
| 2. |
Tests for the crossreactivities of proteins expressed in plaques formed by phages in the library; and
|
| 3. |
An analysis of DNA sequences of the mutant genes encoding proteins with altered crossreactivities.
