Anti bax antibody

Manufactured by Santa Cruz Biotechnology
Sourced in United States

The Anti-Bax antibody is a laboratory reagent used to detect the Bax protein. Bax is a pro-apoptotic member of the Bcl-2 protein family that plays a role in the regulation of programmed cell death. The Anti-Bax antibody can be used in various techniques, such as Western blotting, immunohistochemistry, and immunofluorescence, to analyze the expression and localization of the Bax protein in biological samples.

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.
