Used in research settings to detect and quantify Annexin V levels in biological samples, this ELISA kit is particularly valuable in studies related to apoptosis, or programmed cell death. Annexin V has a high affinity for phosphatidylserine, which translocates to the outer leaflet of the cell membrane during early apoptosis. By measuring Annexin V, researchers can assess cell death in various experimental conditions, including drug toxicity, cancer therapy responses, and immune system regulation. It is commonly applied in immunology, oncology, and pharmacology research to better understand cellular mechanisms and evaluate treatment efficacy in vitro. The kit provides a sensitive and specific method for monitoring apoptotic activity without the need for flow cytometry.
