Creative Bioarray's normal Human Bladder Epithelial Cells - Apex, when grown in LIUro A culture medium, provide an ideal culture model for the study of bladder biology. Cell Features: Human Bladder Epithelial Cells -Dome are cryopreserved as secondary cells, e.g. cells are isolated from the dome region of human bladder tissue and expanded in culture vessels twice before being harvested for cryopreservation. Human Bladder Epithelial Cells -Apex are cryopreserved as secondary cells, e.g. cells are isolated from the apex/neck/trigone region of human bladder tissue and expanded in culture vessels twice before being harvested for cryopreservation. Bladder cells are not exposed to phenol red or antimicrobials when cultured in Creative Bioarray medium. Creative Bioarray guarantees performance and quality.
