Description：Tonsil epithelium is a heterogeneous lymphoid organ containing two different types of actively differentiating epithelia, the lining stratified squamous epithelium and the reticulated crypt, or lymphoepithelium. The tonsil crypts represent a specialized compartment, important in the immunological functions of the tonsil because of the immediate proximity of the epithelial and lymphoid tissues. In Situ staining of tonsil epithelium suggests that expression of the simple epithelial keratins K8, K18 and K19 is located to the crypt epithelial cells. Cell culture of tonsil epithelium produces heterogeneous squamous epithelial culture in which differentiation appears to be ongoing and keratin expression patterns are consistent with those found in tonsil epithelial cells in situ. HTonEpiC from AcceGen Research Laboratories are isolated from human normal tonsil tissue. HTonEpiC are cryopreserved at passage one culture and delivered frozen. Each vial contains >5×10^5 cells in 1 ml volume. HTonEpiC are characterized by immunofluorescent method with cytokeratine antibodies. HTonEpiC are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HTonEpiC are guaranteed to further culture at the conditions provided by AcceGen Research Laboratories.；
Quality Control：All cells test negative for mycoplasma, bacteria, yeast, and fungi；
Application：For research use only.
