Technical Articles

This article focuses on the molecular characteristics and biological functions of Fc fusion proteins, systematically elaborating on the structural composition and dimerization mechanisms of IgG antibody constant fragments as affinity tags, analyzing the technical advantages of Fc fusion proteins in improving solubility, extending half-life, enhancing expression and secretion, and facilitating detection and purification, and discussing the broad applications of Fc fusion proteins in drug discovery, drug delivery, vaccine design, and receptor-ligand interaction research.

FITC-Labeled CEACAM-5/CD66e Fc Chimera is a recombinant protein tool consisting of the extracellular domain of human carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM-5/CD66e) fused to the Fc fragment of immunoglobulin G (IgG) and labeled with fluorescein isothiocyanate (FITC).

FITC-Labeled CD38 Fc Chimera is a recombinant protein tool that combines the extracellular domain of human CD38 with the Fc fragment of immunoglobulin G (IgG) and is labeled with fluorescein isothiocyanate (FITC). As a specific detection probe for the multifunctional immunomodulatory receptor CD38, it is non-pathogenic but serves as a core experimental reagent in key disease research areas such as multiple myeloma, autoimmune diseases, metabolic disorders, viral infections, and age-related immune decline.
