Abstract: Methods and kits for detecting acylated proteins produced by cells that have been cultured or by cells within an organism are provided. Also provided are methods and kits for detecting acylated proteins produced by cells where affinity purification tags are that facilitate detection are used. Compounds useful for the detection of acylated proteins are also provided.

Abstract: A method for relative positioning and locating persons and device thereof, which uses a GPS (Global Positioning System) to lock relative position coordinate data of a plurality of unit devices or a single unit device, and the data is saved within a memory unit, whereafter a wireless communication transmission method is used to mutually connect data (including identification data and coordinate data) between each of the unit devices. Finally, central processor units carry out calculations on and comparison of the data, and an operating unit switches to the desired corresponding unit devices, thereby enabling a display unit to rapidly display relative direction and distance between the corresponding unit devices, thus achieving the objective to rapidly locate persons.
