About IFN-gamma
This gene encodes a soluble cytokine that is a member of the type II interferon class. The encoded protein is secreted by cells of both the innate and adaptive immune systems. The active protein is a homodimer that binds to the interferon gamma receptor which triggers a cellular response to viral and microbial infections. Mutations in this gene are associated with an increased susceptibility to viral, bacterial and parasitic infections and to several autoimmune diseases. [provided by RefSeq, Dec 2015]

About PE-eFluor 610
PE-eFluor™ 610 (PE-eF610, RPE-eF610) from Thermo Fisher Scientific is an orange-emitting tandem fluorophore that combines pycoerythrin (PE) and eFluor™ 610. The donor molecule, PE can be excited by the 488-nm blue, 532-nm green, or 561-nm yellow-green laser and and transfers energy to the acceptor molecule, eF610, which emitts light that can be captured with a 610/20 nm bandpass filter. PE-eF610 has an excitation peak at 565 nm and an emission peak at 607 nm, and is suitable alternative to PE-Texas Red®. PE-eF610 is mainly used for flow cytometry. This tandem is often a great option because of PE is excitable by multiple lasers due to its broad excitation spectrum and the eFluor™ 610 acceptor molecule emits brightly in the Orange/Red spectrum. Many cytometers are commonly set up with the 610/20 bandpass filter that can detect this fluorophore's emission. This dye is part of the larger eFluor™ dye family, developed by eBioscience which is now part of ThermoFisher Scientific.
