Description Immortalized Monkey Primary Dermal Fibroblasts from Cell Biologics are isolated from Monkey skin tissue 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 Monkey Primary Dermal Fibroblasts from Cell Biologics are characterized by their spindle morphology and immunofluorescent staining with anti-fibroblast-specific protein 1 or anti-Vimentin antibody. These cells are negative for mycoplasma, bacteria, yeast, fungi, HIV-1, hepatitis B and hepatitis C 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 with extended life span. The 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. Documents MK-6068IM Cell-Culture-Protocol-CB 1708462493 1698246847 Disclaimer Investigators should handle the cells received from Cell Biologics with caution and treat all primary cells as potential pathogens, since no test procedure can completely guarantee the absence of infectious agents.
