Flag Tag (DYKDDDDK) is a ubiquitous fusion peptide tag widely deployed for recombinant protein detection, localization, and pull-down in molecular cloning and cell protein research. CSB-MA000021M0m is a mouse monoclonal IgG2a antibody generated against KLH-conjugated Flag synthetic peptide, purified via Protein G chromatography with over 95% purity. Backed by five published citations from independent studies, it demonstrates proven utility in real-world recombinant protein workflows beyond stringent in-house manufacturing standards that ensure high purity, lot-to-lot stability, and precise Flag recognition with minimal cross-reactivity. As a high-performance tag antibody, it outperforms competing commercial antibodies in sensitivity and dilution range. Western blot clearly detects as low as 0.39 ng Flag-tagged protein and delivers distinct bands at ultra-high dilution up to 1:320000 across diverse fusion molecular weights, immunofluorescence generates specific green signals in Flag-transfected 293T cells with blank negative controls, and IP efficiently enriches Flag fusion protein from transfected HEK-293/293F lysate with no signal in isotype control groups. Validated for ELISA, WB, IF, and IP, this antibody supplies flexible dilution parameters to support full-spectrum recombinant protein characterization workflows.
