CASP9 Antibody, HRP conjugated

What is Caspase-9 (CASP9) and what is its biological significance?

Caspase-9 is a critical initiator caspase involved in the intrinsic pathway of apoptosis. It functions as part of the apoptotic activation cascade responsible for executing programmed cell death. Upon binding to Apaf-1 (Apoptotic protease activating factor 1), caspase-9 becomes activated and subsequently cleaves and activates the effector caspases, primarily caspase-3 and caspase-7 . This proteolytic activity is essential for the execution phase of apoptosis.

Caspase-9 is also known by several other names including APAF-3, ICE-LAP6, and MCH6 . The protein is initially synthesized as an inactive procaspase (approximately 47 kDa) that requires proteolytic processing to generate the active enzyme, which functions as a heterotetramer . Importantly, caspase-9 exhibits ABL1/c-Abl-dependent promotion of DNA damage-induced apoptosis and cleaves poly(ADP-ribose) polymerase (PARP) .

What is an HRP-conjugated antibody and what advantages does it offer for research?

An HRP-conjugated antibody refers to an antibody that has been chemically linked to horseradish peroxidase enzyme. This conjugation enables direct detection of the target protein without the need for secondary antibody incubation steps. When the antibody binds to its target (in this case, caspase-9), the attached HRP enzyme can catalyze a colorimetric, chemiluminescent, or fluorescent reaction when provided with an appropriate substrate.

The primary advantages of HRP-conjugated antibodies include:

These advantages make HRP-conjugated CASP9 antibodies particularly valuable for time-sensitive experiments and high-throughput research applications .
