Penicillin is a type of antibacterial drug that is widely used in medical and laboratory settings. It is a naturally occurring substance produced by certain fungi, and it is effective against a variety of bacterial infections. Penicillin works by inhibiting the growth and reproduction of bacteria, making it a valuable tool for researchers and medical professionals.

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.
