P yap ser127

Manufactured by Cell Signaling Technology
Sourced in United States

P-YAP(Ser127) is a laboratory reagent used in cell and molecular biology research. It is an antibody that specifically recognizes the phosphorylated form of the Yes-associated protein (YAP) at serine 127 residue. This phosphorylation event is a key regulatory mechanism for the activity and subcellular localization of the YAP transcriptional co-activator.

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.
