[User Manual] PathHunter® Detection Kit
- File Name/Number:
The PathHunter Detection Kit is to be used with PathHunter Cell Lines or cell lines made with ProLabel/ProLink expression or cloning vectors. The kit is easy-to-use and has been successfully run in both 96-well and 384-well microplate format. The resulting signal is chemiluminescent and is read with any standard plate reader. PathHunter products utilize the Enzyme Fragment Complementation (EFC) technology for studying protein protein interactions, protein translocation, receptor trafficking, and receptor internalization, all of which involve the complementation of two beta-galactosidase fragments. The larger beta-gal fragment is called Enzyme Acceptor (EA) and the smaller fragment is termed Enzyme Donor (ED; also known as ProLabel or ProLink). The two fragments are inactive when apart. However, when they complement, they form a functional enzyme that hydrolyzes the substrate to generate a chemiluminescent signal. The detection reagents do not contain either the EA or ED fragments of beta-gal, and therefore must be used in conjunction with cells that express both components in order to obtain a detectable signal.
