Anti parp1

Manufactured by Proteintech
Sourced in China, United States

Anti-PARP1 is a laboratory reagent used to detect the presence of the PARP1 protein in biological samples. PARP1 is a nuclear enzyme involved in various cellular processes, including DNA repair, genomic stability, and cell death. The Anti-PARP1 reagent can be used in techniques such as Western blotting, immunohistochemistry, and immunoprecipitation to study the expression and localization of PARP1 in different cell types and conditions.

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.
