Alanine aminotransferase

Manufactured by Nanjing Jiancheng
Sourced in China

Alanine aminotransferase (ALT) is an enzyme that catalyzes the transfer of an amino group from alanine to alpha-ketoglutarate, producing pyruvate and glutamate. ALT is primarily found in the liver and is commonly used as a biomarker to assess liver function.

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.
