The Mouse CD40 Monoclonal Antibody (APC Conjugated) FGK4.5 (FGK4.5-AGEL0784) is a specialized reagent designed for research applications involving the CD40 protein, a cell surface receptor crucial for immune system activation. This monoclonal antibody, characterized by its specificity and high affinity, is conjugated with APC for fluorescence-based detection methods, providing a valuable tool for flow cytometry and immunofluorescence analyses.CD40, a member of the TNF receptor superfamily, is involved in various immune functions, including B cell activation, antibody production, and antigen presentation.
Its role in regulating immune responses and inflammation underscores its importance in studies related to immunology, infectious diseases, and autoimmune disorders. Utilizing the FGK4.5 monoclonal antibody allows for precise detection and characterization of CD40 expression in different cell types, making it an essential reagent for investigating immune system interactions and developing targeted therapeutic strategies.
Each lot of this antibody is quality control tested by flow cytometric analysis. Please check your vial before the experiment. Since applications vary, the appropriate dilutions must be determined for individual use. We suggest each investigator should titrate the reagent to obtain optimal results [The recommended concentration is 0.1-1 μg/106 cells in 100 μL volume].

Background:
CD40 is a 48 kD type I transmembrane glycoprotein also known as Bp50. It is a member of the tumor necrosis factor receptor (TNFR) superfamily and is expressed on B cells, basal epithelial cells, macrophages, follicular dendritic cells, endothelial cells, and a subset of CD34+ hematopoietic progenitors. CD40 regulates B cell development/maturation, Ig isotype switching and, in combination with other signals such as IL-4, protects B cells from surface Ig-induced apoptosis and promotes proliferation. Interaction of CD40 with its ligand CD154 (gp39), which is expressed on activated T cells, is important in costimulation and immune regulation.
