Anti-Human ROBO4 F(ab) Stable Cell Line-CHO

Cat.No.: CSC-P1089
Cell Line Description: CHO-Anti-Human ROBO4 F(ab) stable cell line is clonally-derived from a CHO cell line, which has been transfected with an anti-human ROBO4 F(ab) gene to allow expression of the F(ab). It is an example of a cell line transfected using our proprietary CBTGS gene screening and amplification system.
Background: Robo4 is a vascular specific receptor that is a repulsive cue to migrating endothelial cells during vascular development. Guidance and patterning of axons are orchestrated by cell surface receptors and ligands that provide directional cues. Interactions between the Robo receptor and Slit ligand families of proteins initiate signaling cascades that repel axonal outgrowth. In contrast to known neuronal Robo family members, the arrangement of the extracellular domains of Robo4 diverges significantly from that of all other Robo family members. Robo4 is specifically expressed in the vascular endothelium during murine embryonic development; the only Robo family member expressed in primary endothelial cells. Robo4 also has a role in regulating the migration of endothelial cells during tumor angiogenesis.
Growth Properties: Suspension
Morphology: Epithelial-like
Species: Human
Host Cell: CHO
Propagation: Complete growth medium: Serum-free MediumAtmosphere: air, 95%; carbon dioxide (CO2), 5% Temperature: 37 °C
Starting Cells From Frozen Cell Stock: 1. Remove the packaging cell lines from liquid nitrogen and carry out a quick thaw. Float the cells in the 37 °C water bath for 2 minutes until nearly (80%) thawed. Once cells are thawed, it is important to dilute the cells 1:10 in growth media immediately to reduce the potentially toxic effects of the DMSO preservative on the cells.2. Clean the outside of the vial with 70% ethanol before opening.3. Remove the cells from the vial and add slowly into a 15 ml conical tube containing 10 ml pre-warmed media. 4. Centrifuge for 5 minutes 300 xg to pellet cells and remove the supernatant.5. Add 14 ml of media and transfer cells to a T25 shaker flask.6. Place the cells in the 37 °C incubator with 5% CO2.7. Allow incubation for 3-4 days to reach confluence. The cells will grow well over a period of several days in culture at 37 °C.
Subculturing: 1. Centrifuge for 5 minutes 300 xg and discard culture medium.2. Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.3. Add appropriate aliquots of the cell suspension to new culture vessels.Incubate cultures at 37 °C.Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:8 is recommended Medium Renewal: 2 to 3 times per week
Mycoplasma: Mycoplasma Status: Negative (MycoAlert Kit)
Freeze Medium: Complete growth medium 90%; DMSO, 10%
Storage: Liquid nitrogen vapor phase
Preservation: 1. Detach cells from culture dish according to the Sub-Culture Procedure.2. Resuspend cells at a density of 5 x 10^6 cells/mL in freeze medium.3. Aliquot 1 mL cells into cryogenic vials.4. Place vials in a freezing container and store at –80 °C overnight.5. Transfer vials to liquid nitrogen for long term storage. If properly stored, cells should remain stable for years.
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.
