Welcome to UBPONE!
Name of Cells: Conditionally Immortalized Human Retinal Pigment Epithelial Cells
Catalogue Number: (HRPEs) UBP-0063
Product Format: Frozen Vial
Cell Number: > 5 x 105cells/vial
General Information: HRPEs (UBP-0037) are initiated by dissecting Retinal Pigment tissue and digestion with collagenase. CI-HRPEc (UBP-0063) are selected from Puromycin resistant HRPEs after infected with lentiviruses expressing SV40 LT under the control of TetON system. CI-HRPEs are maintained with proliferative capacity in the presence of DoxycyclineNOTE1 in HRPEs growth medium (HRPEs growth medium, contains 10% serum and growth supplements, UBP-33).
Characterization of the cells :HRPEs are positive for REPs-specific markers CRALBP and RPE-65 HRPEs are negative for HIV-1, HBV, HCV, and mycoplasma.
Product Use: HRPEs are for research use only NOTE3. Shipping: Frozen Vials in Dry Ice packages.
Handling of Arriving Cells :When you receive the cells in a frozen vial, you can transfer the vial of cells into a -80ºC freezer for short-period storage or a liquid nitrogen tank for long-term storage. Thaw the cells in a 37°C water bath, and then quickly transfer the cells into a T75 flask with 15 ml MSCGM in the presence of 1ug/ml of Doxycycline and incubated overnight in a 37ºCNOTE2 CO2 incubator and change the medium next day (15 ml complete MSCGM) and every other thereafter.
Rinse the cells in T75 flask with 15ml HBSS (Room Temperature, RT) twice.
NOTE 1: To minimize the effect of SV40 LT antigen for your studies, cells could be cultured in the absence Doxycycline for 3-5 days before your final experiments.
NOTE 2: Although wild type SV40 LT antigen is used for cell immortalization, we noticed that the immortalized cells are growing better at 33-34ºC, we encourage the end users to switch to 33-34ºC if cells are growing slower at 37ºC.
