Apoptosis Assays for Advanced High Throughput Flow Cytometry
Simultaneous Measurement of Apoptotic Markers
Apoptosis Pathway
Apoptosis is an essential process for normal tissue development and homeostasis by which cells undergo timely programmed cell death. Aberrations in apoptotic signaling are implicated in a range of human pathologies including cancer, autoimmune disease and neurodegeneration. Induction of apoptosis leads, in most cases, to the depolarization of mitochondria, the activation of caspases and plasma membrane alterations. The ability to simultaneously measure a multitude of apoptotic markers allows confirmation of pathway and insight into mechanism of action over time.

Assay Concept
Figure 1. Apoptotic markers measured by the iQue® Human 4-Plex Apoptosis Kit. 1) Mitochondrial depolarization, 2) Caspase 3/7, 3) Annexin V and 4) Non-viable. The kit components can be utilized either separately or combination in a no wash format. Apoptosis reagents can also be multiplexed with other iQue® reagents in no wash assays.
Key Advantages
Detect and confirm apoptosis through different pathways using the mix and match reagents.
Gain a robust determination of apoptosis progression and insight into mechanism of action.
