[Interaction of anti-TNF-alpha monoclonal antibodies E7H2 with mutant and hybrid proteins]
A number of hybrid proteins containing amino acid sequences of human lymphotoxin and human and mouse tumor necrosis factors were obtained by means of genetic engineering. By using these proteins, an antigenic determinant in the molecule of human tumor necrosis factor for monoclonal antibodies E7H2 (MAb E7H2), previously developed against this factor was localized. It was demonstrated by Western blot analysis that the MAb E7H2-binding site is located in the sequence region 37-49 of human tumor necrosis factor and includes the sequence Val41GluLeuArg44 directly interacting with MAb E7H2.
