Apoptosis Assay
Investigate apoptotic pathways with RayBiotech's assay kits and related products. Our high-quality kits enable confident study of programmed cell death. From screening apoptosis-related proteins to detecting individual targets, our comprehensive offerings empower researchers to investigate apoptotic processes with ease and efficiency, right at the bench.

Detect Apoptotic Events with Confidence
Apoptosis, or programmed cell death, is a fundamental biological process where cells undergo an orderly sequence of events leading to their self-destruction. This process is crucial for maintaining cellular homeostasis, regulating the immune system, and eliminating damaged or diseased cells. Key pathways involve mitochondrial signals and death receptors, regulated by pro-apoptotic molecules (Bax, Bid, Bak, BAD) and anti-apoptotic molecules (Bcl-xL, Bcl-2). The p53 protein also plays a crucial role by initiating cell death in response to stress and DNA damage. Understanding these pathways is vital for medical research and therapy development.
RayBiotech provides comprehensive apoptosis assay kits to study apoptotic pathways. Our offerings include the RayBio® Human Apoptosis Antibody Array Kit for multi-analyte detection of 43 apoptosis-related proteins, ELISAs for single analyte detection (including p53, p27, HSP27, TRAIL, Bcl-w, BAD, cIAP-2, and Smac/Diablo), and flow cytometry-based assays for precise, sensitive detection.
