Functional characterization of odorant receptors from the moth Eriocrania semipurpurella : A comparison of results in the Xenopus oocyte and HEK cell systems
The Xenopus oocyte and the Human Embryonic Kidney (HEK) 293 cell expression systems are frequently used for functional characterization (deorphanization) of insect odorant receptors (ORs). However, the inherent characteristics of these heterologous systems differ in several aspects, which raises the question of whether the two systems provide comparable results, and how well the results correspond
