Odorant response assays for a heterologously expressed olfactory receptor.


Odorant responsiveness of a mouse olfactory receptor, mOR-EG, was investigated in various heterologous cells using a variety of detection methods. Odorant-induced Ca(2+) response was observed in HEK293 cells that coexpressed mOR-EG and the promiscuous G protein, G alpha 15. Without G alpha 15, a robust increase in cAMP level was observed upon odorant… (More)
