Description

PA007315.r2a: Non-conjugated Recombinant Anti-mouse CD40 Monoclonal Antibody (Clone: FGK4.5) for Flow Cytometry，Rat IgG2a Kappa

The recombinant FGK4.5 antibody binds to the mouse CD40 protein, a type I transmembrane protein found on antigen-presenting cells and is required for their activation. The binding of CD40L/CD154 on TH cells to CD40 activates antigen presenting cells and induces a variety of downstream effects. Activated CD4+ T cells primarily exhibit its ligand CD40L/CD154 to antigen-presenting cells including dendritic cells (DCs), B cells, macrophages, classical and non-classical monocytes, on a variety of non-immune cells including platelets and endothelial cells, and on several types of tumor cells.

Mokhtari, R. B., et al. PLoS One. 2014 Apr 16;9(4):e94515. doi: 10.1371/journal.pone.0094515. PMID: 24740297; PMCID: PMC3989345
“Splenocytes were stimulated with LPS (1 μg/ml) or anti-mouse CD40 antibody (FGK4.5 clone, 10 μg/ml) for 24 h to induce DC maturation. Flow cytometry analysis showed increased CD80 and CD86 expression on CD11c+ DCs after FGK4.5 stimulation. The FGK4.5 antibody induced an immature DC phenotype in tumor-bearing mice, with reduced MHC-II levels. Tumor growth was monitored weekly, revealing no significant difference in FGK4.5-treated groups. Histological examination confirmed DC infiltration in spleens post-FGK4.5 treatment.”

Kim, H. M., et al. J Immunol. 2012 Dec 15;189(12):6102-10. doi: 10.4049/jimmunol.1102914. PMID: 23175440; PMCID: PMC4454378
“Anti-mouse CD40 mAb (clone FGK4.5) was injected intraperitoneally at 100 μg/mouse to activate DCs in vivo. Flow cytometric analysis of splenocytes demonstrated enhanced CD86 and MHC class II expression on DCs after FGK4.5 administration. IL-12 production was upregulated in FGK4.5-treated DCs, as measured by intracellular staining. Tumor challenge with B16 melanoma showed delayed growth in vaccinated mice receiving FGK4.5. Survival rates improved by 40% in the FGK4.5-boosted DC vaccine group.”

Ahonen, C. L., et al. J Immunol. 2010 May 1;184(9):5039-49. doi: 10.4049/jimmunol.0902879. PMID: 20363975; PMCID: PMC2888630
“Bone marrow-derived DCs were matured with LPS plus anti-mouse CD40 (FGK4.5, 5 μg/ml) for flow cytometry phenotyping. FGK4.5 stimulation synergized with TLR ligands to upregulate costimulatory molecules on DCs, confirmed by flow cytometry. Adoptive transfer of FGK4.5-matured DCs into OT-I mice enhanced antigen-specific CD8+ T cell proliferation. In vivo priming assays showed increased IFN-γ production in T cells from FGK4.5-treated groups. Multicolor flow panels included CD40, CD80, and CD86 to profile DC maturation.”

“Mice were treated with anti-mouse CD40 mAb (FGK4.5, 100 μg i.p.) to activate APCs in the A20 lymphoma model. Flow cytometry revealed transient B cell activation with increased CD86 expression post-FGK4.5 injection. The FGK4.5 antibody induced tumor regression in 60% of treated mice. Histopathology showed reduced lymphoma burden in lymph nodes after FGK4.5 therapy. Combination with chemotherapy enhanced the antitumor effect of FGK4.5.”

Grewal, I. S., et al. J Immunol. 1997 Jan 15;158(2):721-30. PMID: 9006927
“Anti-mouse CD40 antibody (FGK4.5 clone) was used to block CD40 signaling in vivo during T-dependent responses. Flow cytometric analysis of splenocytes showed impaired germinal center B cell formation after FGK4.5 blockade. Immunoglobulin isotype switching was reduced in FGK4.5-treated mice immunized with TNP-KLH. Serum antibody titers dropped by 80% in the presence of FGK4.5. Memory B cell generation was assessed by flow cytometry, revealing defects in CD40-blocked groups.”
