The Myc Luciferase Reporter Lentiviruses are replication incompetent, HIV-based, VSV-G pseudotyped lentiviral particles that are ready to transduce almost all types of mammalian cells, including primary and non-dividing cells. The particles contain a firefly luciferase gene driven by the Myc response element located upstream of the minimal TATA promoter (Figure 1) and an antibiotic selection gene (puromycin) for the selection of stable clones. After transduction, the Myc signaling pathway in the target cells can be monitored by measuring the luciferase activity.

The lentivirus particles were produced from HEK293T cells. They are supplied in cell culture medium containing 90% DMEM + 10% FBS.
Background
The Myc signaling pathway plays an important role in cell proliferation, differentiation, transformation and apoptosis. c-Myc is a transcription factor that heterodimerizes with Max to regulate Myc signaling pathway-responsive genes. Genetic alterations in MYC have been linked to a number of human cancers, including Burkitt’s lymphoma, cervical, ovarian, breast, lung and pancreatic carcinomas. Thus, Myc is a promising therapeutic target for cancer treatment. Myc can be activated by the Wnt/β-catenin pathway.
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.
Growth Media
For best results, it is highly recommended to use these validated and optimized media from BPS Bioscience. Other preparations or formulations of media may result in suboptimal performance.
Thaw Medium 7 (BPS Bioscience, #60185): McCoy’s 5A medium with 10% FBS, 1% Penicillin/Streptomycin.
Assay Medium 7B (BPS Bioscience, #79718): Opti-MEM I + 0.5% FBS + 1% non-essential amino acids + 1 mM sodium pyruvate + 1% penicillin/ streptomycin.
Applications
Screen for activators or inhibitors of Myc signaling pathway in transduced target cells
Generate Myc Luciferase Reporter stable cell line (puromycin resistant)
Shipping Temperature
-80°C
Notes
Biosafety The lentiviruses are produced with the third generation SIN (self-inactivation) lentivector which ensures self-inactivation of the lentiviral construct after transduction and after 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 and are not present in the lentivirus particle. Although the pseudotyped lentiviruses are replication-incompetent, they require the use of a Biosafety Level 2 facility. BPS Bioscience recommends following all local federal, state, and institutional regulations and using all appropriate safety precautions.
