B16F10-mNIS-Neo/eGFP-Puro

Species: Mouse

Cell type: Melanoma

Transgenes: Murine sodium iodide symporter (mNIS) with neomycin resistance (Neo) for selection with G418 and enhanced green fluorescent protein (eGFP) with puromycin resistance (Puro) for selection with puromycin

Media: DMEM, 10% FBS, 1% Pen/Strep, 0.8mg/mL G418, 1 µg/mL puromycin

Description: B16F10-mNIS-Neo/eGFP-Puro is a polyclonal population of the murine melanoma cell line B16F10 (ATCC® CRL-6475) transduced with 1) LV-mNIS-P2A-Neo (LV025) encoding the murine sodium iodide symporter (mNIS) cDNA under the spleen focus-forming virus (SFFV) promoter linked to the neomycin resistance gene (Neo) via a P2A cleavage peptide and 2) LV-eGFP-PGK-Puro (LV031) encoding enhanced green fluorescent protein (eGFP) cDNA under the SFFV promoter and the puromycin resistance gene (Puro) under control of the PGK promoter.

The lentiviral vector used is a self-inactivating (SIN) vector 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).

Cell Line Authentication: Authentication of the parental B16F10 cell line was performed by short tandem repeat (STR) profiling with 27 STR loci. STR profiling of B16F10 cells are verified and there is no interspecies cross contamination detected.

Recommended uses:

In vitro: This is a high mNIS/eGFP expressing cell line suitable for use as a positive control cell line in iodine uptake assays and fluorescence assays to verify NIS or GFP expression respectively in your lentiviral transduced cells.

In vivo: B16F10 cells form metastases in the lungs of mice. The in vivo growth of these metastases can be monitored using noninvasive, high-resolution 3D PET/SPECT imaging or optical imaging for GFP fluorescence.

Note: In-life imaging for GFP fluorescence is not recommended due to high background autofluorescence. Tissues may be harvested post mortem for analysis by conventional microscopy.

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

NIS Function Assay (Iodine Uptake): Cells were incubated with I-125 for 1h in the presence or absence of KClO4, an inhibitor of NIS-mediated iodine uptake. Radioiodine concentrated within the cells was measured with a gamma counter

 

Flow Cytometry for eGFP: B16F10-mNIS-Neo/eGFP-Puro (green) or control cells (grey) were fixed with paraformaldehyde and analyzed by flow cytometry (20,000 events).
