The STAT5 Luciferase Reporter Lentivirus are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to be transduced into almost all types of mammalian cells, including primary and non-dividing cells. The particles contain a firefly luciferase gene under the control of STAT5-responsive element located upstream of the minimal TATA promoter (Figure 1). After transduction, activation of the STAT5 signaling pathway in the target cells can be monitored by measuring the luciferase activity.

Two vials (500 μl x 2) of STAT5 luciferase reporter lentivirus at a titer ≥1 x 10^7 TU/ml. The titer will vary with each lot; the exact value is provided with each shipment.
The lentiviruses were produced from HEK293T cells and are provided in medium containing 90% DMEM + 10% FBS.

Storage/Stability
Lentiviruses are shipped with dry ice. For long-term storage, it is recommended to store the lentiviruses at -80°C for up to 12 months from date of receipt. Avoid repeated freeze/thaw cycles. Titers can drop significantly with each freeze/thaw cycle.
Instructions for Use
See assay protocol for detailed instructions.
Shipping Temperature
-80°C
Warnings
Biosafety
The lentiviruses are produced with the second generation SIN (self-inactivation) lentivector which ensures self-inactivation of the lentiviral construct after transduction and integration into the genomic DNA of the target cells. 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.
