Applications: 1. Transient expression of FcER1G in target cells.
2. Generation of stable cell line expressing FcER1G with Puromycin selection as an accessory protein to stabilize the surface expression of other Fc receptors.
Description: FcER1G is an adapter protein containing an immunoreceptor tyrosine-based activation motif (ITAM) that transduces activation signals from various immunoreceptors. As a component of the high-affinity immunoglobulin E (IgE) receptor, FcER1G mediates allergic inflammatory signaling in mast cells. FcER1G is also a subunit of other Fc receptors.
The FcER1G Lentivirus are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to be transduced into almost all types mammalian cells, including primary and non-dividing cells. The particles contain a FcER1G gene (NM_004106.2) driven by an EF1α promoter.
Formulation: The lentiviruses were produced from HEK293T cells in the medium containing 90% DMEM + 10% FBS.
Storage Stability: Lentiviruses are shipped with dry ice. For long term storage, it is recommended to store the virus at -80°C. Avoid repeated freeze-thaw cycles. Titers can drop significantly with each freeze-thaw cycle.
Supplied As: Two vials (500 µl x 2) of lentivirus at a titer ≥5 x 106 TU/ml. The titer will vary with each lot; the exact value is provided with each shipment.
Warnings: Biosafety: None of the HIV genes (gag, pol, rev) will be expressed in the transduced cells, as they are expressed from packaging plasmids lacking the packing signal. Although the pseudotyped lentiviruses are replication-incompetent, they require the use of a Biosafety Level 2 facility. BPS recommends following all local federal, state, and institutional regulations and using all appropriate safety precautions.
Biosafety Level: BSL-2
