Description

Immortalized GFP-Expressing Mouse Primary Esophageal Fibroblasts from Cell Biologics are isolated from the esophageal tissues of pathogen-free laboratory C57BL/6 mice and grown in gelatin pre-coated tissue culture flask with Cell Biologics’ Complete Growth Medium. Cells at passage 2-3 are harvested from flasks and cryo-preserved in vials. Each vial contains 0.5x10⁶ cells per ml and is delivered frozen. Immortalized GFP-Expressing Mouse Primary Esophageal Fibroblasts are characterized by their spindle morphology and immunofluorescence staining with anti-FSP1/S100A4 (Millipore USA) antibody. These cells are negative for bacteria, yeast, fungi, and mycoplasma and can be expanded for more than 10 passages at a split ratio of 1:2 under the cell culture conditions specified by Cell Biologics. Repeated freezing and thawing of cells are not recommended.

Immortalized cells from Cell Biologics are derived from primary cells expressing GFP. These primary cells are immortalized by over-expression of the large T-antigen of the simian virus (SV40) or human telomerase reverse transcriptase (hTERT).

Suggested Medium

M2267 Complete Fibroblast Medium w/ Kit – 500 ml

Storage

Cryopreserved cells are shipped with dry ice overnight. Upon arrival, transfer frozen cells to liquid nitrogen (-180°C) immediately until ready for use. Live cell shipment is also available on request. Primary cells can never be kept at -20 °C or -80 °C freezer.

Disclaimer

Investigators should handle the cells with caution and treat all animal cells as potential pathogens, since no test procedure can completely guarantee the absence of infectious agents.
