Caspase-3 stands as a central executioner in the apoptotic cascade, serving as the convergence point for both intrinsic and extrinsic cell death pathways. This cysteine protease cleaves critical cellular substrates during programmed cell death, making it an essential marker for apoptosis research across cancer biology, developmental studies, and therapeutic development. Understanding caspase-3 activation and expression patterns provides researchers with fundamental insights into cell fate decisions and disease mechanisms.
This recombinant monoclonal antibody, generated against a synthetic peptide encompassing both active and pro-caspase-3 sequences, offers the reproducibility that demanding experimental workflows require. As a sequence-defined reagent produced through recombinant technology, it delivers consistent performance across experiments and eliminates the lot-to-lot variability that can complicate long-term studies or multi-site collaborations. The rabbit IgG format, purified by affinity chromatography, ensures high specificity for your target.
Validation studies demonstrate reliable performance across multiple applications. Western blot analysis at 1:1000 dilution successfully detected caspase-3 in HeLa, HEK293, and Ntera-2 cell lysates, with the expected 32 kDa band corresponding to the pro-caspase form. Additional bands observed at 55 kDa and 130 kDa likely represent post-translationally modified forms or protein complexes, which is consistent with caspase-3's known behavior in cellular contexts. For tissue-based studies, immunohistochemistry validation in paraffin-embedded human kidney sections at 1:100 dilution confirms suitability for examining caspase-3 expression in fixed specimens.
Whether investigating apoptotic signaling in cancer models, examining metabolic stress responses, or characterizing cell death pathways, this antibody provides a dependable tool for researchers studying human samples across ELISA, western blot, and immunohistochemistry applications.
