Caspase-3 stands as one of the most critical executioner caspases in the apoptotic pathway, serving as a convergence point for both intrinsic and extrinsic cell death signaling cascades. This cysteine protease cleaves essential cellular substrates including PARP, ultimately driving the morphological and biochemical hallmarks of apoptosis. Given its central role in programmed cell death, Caspase-3 remains indispensable for researchers investigating cancer biology, neurodegenerative diseases, developmental processes, and therapeutic responses across numerous disease models.
This recombinant monoclonal antibody, clone 27D11, offers the reproducibility and consistency that demanding apoptosis research requires. Produced using recombinant technology with a defined sequence, this antibody eliminates the lot-to-lot variability that can compromise longitudinal studies or multi-site collaborations. The human IgG1 isotype format, generated against recombinant human CASP3 protein, ensures reliable target recognition with human sample reactivity.
Validation through flow cytometry demonstrates robust intracellular detection capabilities, as confirmed in HEK293T cells using standard fixation and permeabilization protocols. The flow cytometry data shows clear separation between specific staining and isotype control, supporting dilutions in the 1:50 to 1:200 range for optimal signal-to-noise ratios. Additional validation for ELISA applications provides flexibility for researchers requiring quantitative detection methods.
Supplied in a glycerol-based PBS buffer optimized for long-term stability at -20°C or -80°C, this affinity-purified antibody is well-suited for laboratories studying apoptotic mechanisms, screening pro-apoptotic compounds, or characterizing cell death responses in human experimental systems.
