oxStayGold Sequence

oxStayGold was derived from StayGold with the following mutations: H169Y/C174I/C208I

GenBank: LC601653


The oxStayGold variant of StayGold was engineered to efficiently label the ER from the inside. Because oxStayGold was found to label all subcellular components, including the cytoplasm, very brightly, it has replaced StayGold in many experiments; however, oxStayGold remains a dimer.
