Caspase-9 serves as a critical initiator caspase in the intrinsic apoptotic pathway, functioning as a key component of the apoptosome complex alongside APAF-1 and cytochrome c. Upon activation, this protease triggers the downstream caspase cascade that executes programmed cell death, making it an essential target for researchers investigating apoptosis regulation, cancer biology, and cellular stress responses.
This recombinant monoclonal antibody, clone 2D5, offers the reproducibility and consistency that demanding apoptosis research requires. Generated against a synthetic peptide derived from human CASP9 and produced using recombinant technology, this antibody provides sequence-defined specificity with minimal lot-to-lot variation, ensuring your experimental results remain comparable across studies and time.
Validation across multiple detection platforms demonstrates this antibody's versatility in your workflow. Western blot analysis in HL-60 and LO2 whole cell lysates reveals a clear band at the expected 47 kDa molecular weight corresponding to the full-length procaspase-9 form, with recommended dilutions ranging from 1:500 to 1:5000. Immunofluorescence studies in HepG2 cells confirm cytoplasmic localization patterns consistent with caspase-9's known cellular distribution, while flow cytometry analysis in K562 cells demonstrates reliable intracellular detection following appropriate fixation and permeabilization protocols.
The unconjugated format and affinity-purified preparation provide flexibility for pairing with your preferred secondary detection systems. Whether you are characterizing apoptotic signaling in leukemia models, investigating mitochondrial pathway activation, or screening for modulators of programmed cell death, this antibody delivers the specificity and application range needed to advance your cell biology research with confidence.
