Bloqueio de anticorpos direcionados por um conjugado duplo-funcional de peptídeo antigênico e mimetismo FC-III (DCAF)

Overview

This article presents a detailed protocol for synthesizing a dual-functional conjugate of antigenic peptide and Fc-III mimetics (DCAF1) aimed at eliminating harmful antibodies. The method focuses on selectively blocking the 4G2 antibody to mitigate the antibody-dependent enhancement effect during Dengue virus infection.
