If you want to keep it from one scene to another without destroying it in the transition, you can use this(see doc here)

DontDestroyOnLoad(myObj);

Make it a prefab by right clicking in your assets window and choosing create->prefab, then dragging the object from the Hierarchy onto the empty prefab. You can then use it in any scene by manually adding it or dynamically instantiating it.
