How to use

In Vitro:

The primary structure of Obestatin(human) indicates that it only presented one lysine at position 10, which suggests that it cannot penetrate the cell membrane.

In Vivo:

In adult male mice, intraperitoneal injection of Obestatin(human) suppresses food intake in a timeand dose-dependent manner.
