Normal Human Renal Epithelial Cells, when grown in LIRen Medium, provide an ideal low-serum culture model for the study of renal function, metabolism, nephrotoxicity or cancer research. Renal Cortical Epithelial Cells are cryopreserved as primary cells to ensure the highest viability and plating efficiency. Our Renal Epithelial Cells are quality tested in LIRen Medium to ensure optimal reduced-serum growth over a period of at least 15 population doublings at rates equal to or greater than serum-supplemented medium. Cell Features? Mixed Renal Epithelial, Renal Cortical Epithelial, and Renal Medullary Epithelial are cryopreserved as primary cells isolated from human kidney tissue and expanded in culture vessels once before cryopreservation.Renal Proximal Tubule Epithelial are cryopreserved as secondary cells isolated from human kidney tissue and expanded in culture vessels twice before cryopreservation.All Renal Epithelial Cell types can be grown in a 0.5% serum medium without phenol red or antimicrobials when cultured in LIRen Medium.All Renal Epithelial Cell types are extensively tested for quality and optimal performance.AcceGen Biotech guarantees performance and quality.
