Cat.No. : CSC-RO01243 Host Cell: Mouse pro B cell line (BaF3)
Size: >1x10^6 frozen cells/vial, 1 mL Stability: Stable in culture over a minimum of 10 passages
| Cat. No. | CSC-RO01243 |
| Description | This cell line is engineered to stably overexpress human CD74-ROS1 fusion protein with G2032R mutation in ROS1 region. Expression of human CD74-ROS1-G2032R in this cell line has been analyzed by qPCR. Overexpression of human CD74-ROS1-G2032R render the BaF3 cells to be depended on the activation of CD74-ROS1-G2032R instead of IL-3 supplement. This cell line can grow in the medium without IL-3. |

| Thawing & Subculturing Instructions | 1. Thaw cells by gently swirling in a 37°C water bath. To limit contamination, do not submerge the O-ring and cap. 2. When cells are ~70% thawed (~1 min), transfer the vial into a biosafety cabinet, and wipe the surface with 70% ethanol. Allow tube to dry completely. 3. Transfer the cells gently into a 15 mL conical tube containing 10 mL of pre-warmed culture medium (without antibiotic selection marker). Centrifuge cells at ~125 x g for 5~7 min. 4. Remove supernatant without disturbing the pellet, and resuspend cells in 1 mL culture medium (without antibiotic selection marker). Transfer cells to a 6-well plate containing ~2 mL pre-warmed growth medium (without antibiotic selection marker) or a T25 flask containing 5 mL pre-warmed culture medium (without antibiotic selection marker). 5. Incubate the culture at 37°C with 5% CO2. 6. Subculture: split saturated culture 1:4 ~ 1:6 every 3 days; seed out at about 1~3 x 10^5 cells/mL. |
| Growth Properties | Suspension, round |
| Freeze Medium | Frozen with 70% medium, 20% FBS, 10% DMSO |
| Freezing Instructions | Cells are recommended to generate additional frozen stocks at early passages. Frozen stocks should be preserved in a designated cryopreservation medium or in 70% RPMI 1640 + 20% FBS + 10% DMSO (without antibiotic selection marker). 1. Prepare the freezing medium (70% RPMI 1640 + 20% FBS + 10% DMSO, without antibiotic selection marker) fresh immediately before use. 2. Keep the freezing medium on ice and label cryovials. 3. Transfer cells to a sterile, conical centrifuge tube, and count the cells. 4. Centrifuge the cells at 250 x g for 5 minutes at room temperature and carefully aspirate off the medium. 5. Resuspend the cells at a density of at least 3 x10^6 cells/ml in chilled freezing medium. 6. Aliquot 1 ml of the cell suspension into each cryovial. 7. Freeze cells in the CoolCell freezing container overnight in a -80°C freezer. 8. Transfer vials to liquid nitrogen for long-term storage. |
| Mycoplasma | Negative |
| Format | One frozen vial containing millions of cells |
| Storage | Liquid nitrogen |
| Safety Considerations |
The following safety precautions should be observed. 1. Use pipette aids to prevent ingestion and keep aerosols down to a minimum. 2. No eating, drinking or smoking while handling the stable line. 3. Wash hands after handling the stable line and before leaving the lab. 4. Decontaminate work surface with disinfectant or 70% ethanol before and after working with stable cells. 5. All waste should be considered hazardous. 6. Dispose of all liquid waste after each experiment and treat with bleach. |
