Description Human Primary Small Intestinal Epithelial Cells 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 3 are harvested from flasks and cryo-preserved in vials. Each vial contains 0.5x106 cells per ml and is delivered frozen. Human Primary Small Intestinal Epithelial Cells from Cell Biologics are characterized by immunofluorescent staining with E-cadherin (Catalog No. 610182 from BD), E-Cadherin (Cat# SC-8426, Santa Cruz) or ZO-1 (Catalog No. 617300; from Life Technologies) antibody. These Cells are negative for mycoplasma, bacteria, yeast, fungi, HIV-1, hepatitis B and hepatitis C and can be expanded for 3-5 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. Suggested Medium H6621 Complete Epithelial Cell 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 MSDS.CellBiologics H-6051 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.
