What is flow cytometry?
Flow cytometry is a technique used to analyze the physical and chemical characteristics of cells or particles.
How does Actinomycin D induce apoptosis?
Actinomycin D intercalates into DNA, inhibiting transcription and leading to programmed cell death.
What are early and late apoptotic biomarkers?
Early biomarkers include phosphatidylserine exposure, while late biomarkers include caspase activation and DNA fragmentation.
Can non-experts perform flow cytometry?
Yes, the protocol is designed to be accessible for non-expert users with basic training.
What cell line was used in this study?
The SiHa cervical cancer cell line was used to study apoptosis.
What is the significance of studying apoptosis in cancer?
Understanding apoptosis can help develop targeted therapies and improve cancer treatment outcomes.
