We determined there are two possible regions producing positron-electron annihilation line (PEAL) from the relativistic jet: close to and faraway from the black hole in AGNs and quasars. The PEAL profile has been calculated for several cases. It is expected that future observations with INTEGRAL may discover these lines in order to test the paradigm of active galactic nuclei and quasars.
