Cyclin e

Manufactured by BD
Sourced in Germany, United States

Cyclin E is a lab equipment product that serves as a key regulator of the cell cycle. It plays a critical role in the transition from the G1 phase to the S phase of the cell cycle. Cyclin E binds to and activates the cyclin-dependent kinase 2 (CDK2) enzyme, which is essential for the initiation and progression of DNA replication.

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.
