CD40, a member of the tumor necrosis factor receptor superfamily, serves as a critical costimulatory molecule that orchestrates immune responses through its interaction with CD40 ligand. Expressed on B cells, dendritic cells, monocytes, and various non-immune cell types, CD40 signaling drives B cell activation, germinal center formation, and immunoglobulin class switching. Beyond its classical immunological roles, CD40 has emerged as a significant player in cardiovascular biology and stem cell research, making it a compelling target for investigators exploring diverse physiological and pathological processes.
This recombinant monoclonal antibody, clone 10A12, offers the reproducibility and consistency that demanding experimental workflows require. Generated using recombinant technology and produced in mouse as an IgG2a isotype, this antibody provides sequence-defined specificity against human CD40, eliminating the lot-to-lot variability that can compromise longitudinal studies or multi-site collaborations. Affinity chromatography purification ensures high purity suitable for sensitive detection methods.
Validation studies demonstrate reliable performance across multiple platforms. Immunofluorescence staining has been successfully performed on both A549 lung carcinoma and PC-3 prostate cancer cell lines at 1:30 dilution, revealing clear membrane and cytoplasmic localization patterns when counterstained with DAPI. Flow cytometry analysis using THP-1 monocytic cells confirms robust surface detection at 1:100 dilution, with distinct positive population separation from isotype control, supporting quantitative expression studies.
Whether you are investigating immune checkpoint biology, characterizing tumor microenvironment interactions, or exploring CD40-mediated signaling in cardiovascular or stem cell contexts, this antibody delivers the technical reliability needed to advance your research with confidence.
