Anti-Human KIR3DL1 MAb Stable Cell Line-CHO

Cat.No.: CSC-P0911
Cell Line Description: CHO-Anti-Human KIR3DL1 MAb stable cell line is clonally-derived from a CHO cell line, which has been transfected with an Anti-human KIR3DL1 MAb gene to allow expression of the MAb. It is an example of a cell line transfected using our proprietary CBTGS gene screening and amplification system.
Background: KIR3DL1 (NKB1, CD158e1) is expressed on a subset of natural killer cells and T cells. NKB1 is a 70 kD member of the immunoglobulin superfamily that is expressed at varying levels among individuals. NKB1 is a type I membrane protein containing two immunoglobulin C2 type domains. The interaction of NKB1 with specific HLA B antigens on a target cell (the HLA Bw4 allele, for example) inhibits cytotoxicity and prevents target cell lysis and death. The interactions between KIR and MHC class I are thought to be important in NK and T cell regulation following antigen stimulation. The absence of ligands for KIRs may lower the threshold for activation through activating receptors and increase inflammation and susceptibility to autoimmune disease.
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.
