Annexin 5 fitc apoptosis detection kit c1062

Manufactured by Beyotime
Sourced in China

The Annexin V-FITC Apoptosis Detection Kit (C1062) is a laboratory product that is used to detect and quantify apoptosis, a type of programmed cell death. The kit utilizes Annexin V, a calcium-dependent phospholipid-binding protein, which has a high affinity for phosphatidylserine (PS). During apoptosis, PS is translocated from the inner to the outer leaflet of the plasma membrane, exposing it to the external cellular environment. The kit contains Annexin V conjugated with the fluorescent dye FITC, allowing for the detection of apoptotic cells by flow cytometry or fluorescence microscopy.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
