4T1-Fluc-Neo

Species: Mouse

Cell type: Mammary carcinoma

Transgenes: Firefly luciferase (Fluc) and neomycin resistance (Neo) for selection with G418

Media: RPMI, 10% FBS, 1% Pen/Strep, 0.7 mg/mL G418

Description:

4T1-Fluc-Neo is a polyclonal population of the murine mammary carcinoma cell line 4T1 (ATCC® CRL-2539™) transduced with a lentiviral vector LV-Fluc-P2A-Neo (LV011) encoding the firefly luciferase (Fluc) cDNA under the spleen focus-forming virus (SFFV) promoter linked to the neomycin resistance gene (Neo) via a P2A cleavage peptide

The lentiviral vectors used are self-inactivating (SIN) vectors in which the viral enhancer and promoter has been deleted. Transcription inactivation of the LTR in the SIN provirus increases biosafety by preventing mobilization by replication competent viruses and enables regulated expression of the genes from the internal promoters without cis-acting effects of the LTR (Miyoshi et al., J Virol. 1998).

Mycoplasma Testing:

The 4T1-Fluc-Neo cell line has been tested for mycoplasma contamination and is certified mycoplasma free.

Cell Line Authentication:

The parental 4T1 cell line was authenticated and certified free of interspecies cross-contamination by short tandem repeat (STR) profiling with 27 STR loci.

Recommended uses:

In vitro: This is a high luciferase expressing cell line suitable for use as a positive control cell line in bioluminescence assays to verify luciferase expression in your lentiviral transduced cells.

In vivo: 4T1 cells form tumors post implantation into immunocompromised or syngenic Balb/c mice. The in vivo growth of these tumors can be monitored using noninvasive bioluminescent imaging.

Morphology: Low- and high-density cell morphology (200x)

Luciferase Assay: 104, 105, or 106 cells were placed in wells of a 96-well plate and 0.3 mg of d-luciferin was added to the indicated wells. The plate was immediately imaged using a Xenogen IVIS Spectrum.

107 4T1-Fluc-Neo cells were injected subcutaneously into the right flanks of female NCR athymic mice. Mice were imaged at day 0 on the day of cell implantation and at day 16 using a Perkin Elmer IVIS® Spectrum system, at 10-15 minutes post intraperitoneal injection of D-luciferin at 150 mg/kg. Tumor size was measured using calipers. Data from a representative mouse (ID#3876) is shown
