Abstract: The present invention provides a detection system for a PCR process using FRET which comprises at least two single-labelled Oligonucleotide sequences of differing Tm that hybridize to one another in free solution to form a fluorescent quenched pair, that upon introduction of a complementary sequence to one or both sequences generates a measurable signal, one of the sequences being of a Tm that is below the Ta of the PCR process, the other not being below the Ta of the PCR process.

Abstract: The invention concerns heating metal strips or other coilable strand metal object to an elevated temperature, wherein the metal object is passed in a heating section through a furnace chamber that is made at least partly of an insulating and electrically non-conductive material while being heated through transverse flux induction heating (TFIH) by transverse flux induction heating elements located outside of the chamber which contains a protective non-oxidizing gas or gas mixture. The metal object is of stainless steel that has been cold rolled to a very high degree of surface reflectivity. The cold rolled stainless steel object is passed through the furnace chamber and is heated in the chamber to a processing temperature between 700 and 1200° C. The cold rolled stainless steel object is maintained at that temperature between 700 and 1200° C.
