FITC-Labeled CD19 Fc Chimera is a recombinant protein consisting of the extracellular domain of human CD19 fused to the Fc fragment of immunoglobulin G (IgG) and labeled with fluorescein isothiocyanate (FITC). As a critical tool for B cell research and diagnostics, it does not directly cause disease but serves as an indispensable reagent for studying B cell-related disorders such as B cell lymphoma, leukemia, autoimmune diseases, and immunodeficiency disorders.
