背景信息

Cleaved-Caspase 8 antibodies are essential tools for detecting activated Caspase-8. a key protease in apoptosis and necroptosis regulation. Caspase-8. a member of the cysteine-aspartic acid protease (caspase) family, exists as an inactive zymogen (procaspase-8) in unstimulated cells. Upon activation of extrinsic apoptotic pathways—triggered by death receptors like Fas or TNF receptors—procaspase-8 undergoes dimerization and autoproteolytic cleavage at specific aspartic acid residues (e.g., Asp374 and Asp384 in human Caspase-8). This cleavage generates active fragments (18 kDa and 10 kDa subunits) that initiate downstream caspase cascades, leading to programmed cell death. Cleaved-Caspase 8 antibodies specifically recognize these processed fragments, distinguishing them from the full-length precursor. Researchers use these antibodies in techniques like Western blotting, immunohistochemistry, and flow cytometry to study apoptosis activation in contexts such as cancer, neurodegenerative diseases, or treatment response assays. Their specificity makes them critical for validating Caspase-8 activation in experimental models, drug screening, or mechanistic studies. However, results must be interpreted alongside functional assays, as cleavage alone does not always confirm enzymatic activity. Proper controls, including positive/negative samples and size verification of detected bands, are essential to ensure antibody specificity.
