Application: 1. Transient expression of FcGRIIIA in target cells.
2. Generation of stable cell line expressing FcGRIIIA with Geneticin (G418) selection.
Description: Fc Gamma Receptor IIIa (FcGRIIIA; FcγRIIIA), also known as CD16a, is a low/intermediate affinity receptor for polyvalent immune-complexed IgG. It is involved in phagocytosis, antibody-dependent cytotoxicity and clearance of immune complexes. The human FcγRIIIa displays a dimorphism in the position of residue 158. One allele (V158) encodes a higher Fc affinity receptor variant with a valine at amino acid residue 158, and the other (F158) encodes a lower Fc affinity receptor variant having a phenylalanine at amino acid residue 158.
The FcGRIIIA 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 FcGRIIIA gene (NM_001127593.1; high affinity V158 variant) driven by a CMV 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: 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
