Immortalized Human Primary Small Intestinal Fibroblasts from Cell Biologics are isolated from human small intestinal 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 0.5x10^6 cells per ml and is delivered frozen. Immortalized Human Primary Small Intestinal Fibroblasts 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 is not recommended.

Notes
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.
