NR8383 Cells
Product number:
305200
General information
Description | The cells were cultured in the presence of gerbil lung cell conditioned medium for approximately 8 to 9 months.Subsequently the requirement for exogenous growth factors was lost.The cells exhibit characteristics of macrophage cells.Phagocytosis of zymosan and Pseudomonas aeruginosa, nonspecific esterase activity, Fc receptors, oxidative burst,IL-1, TNF beta and IL-6 secretion, and replicative response to exogenous growth factors.The cells respond to appropriate microbial, particulate or soluble stimuli with phagocytosis and killing.NR8383 cells respond to bleomycin by secreting latent transforming growth factor(TGF beta).Stimulation with bleomycin also increases TGF beta mRNA expression.These cells are sensitive to endotoxin.LPS levels of 1 to 10 ng/mL inhibit replication by 50%.LPS inhibition is nontoxic and reversible even after levels up to 0.001mg/mL for extended periods. |

Handling
Culture Medium | Ham's F12K Medium, w: 2.0 mM L-Glutamine, w: 2.0 mM Sodium pyruvate, w: 2.5 g/L NaHCO3 (Cytion article number 820608a) |
---|---|
Medium supplements | Supplement the medium with 15% FBS |
Passaging solution | Accutase |
Subculturing | Gather the suspension cells in a 15 ml tube and gently wash the adherent cells with PBS lacking calcium and magnesium (use 3-5 ml for T25 flasks and 5-10 ml for T75 flasks). Apply Accutase (1-2 ml for T25 flasks, 2.5 ml for T75 flasks) ensuring full coverage of the cell layer. Allow the cells to incubate at room temperature for 10 minutes. Following incubation, combine and centrifuge both the suspension and adherent cells. After centrifugation, carefully resuspend the cell pellet and transfer the cell suspension into new flasks containing fresh medium. |
Split ratio | 1:2 to 1:4 |
Fluid renewal | 2 to 3 times per week |
Freeze medium | CM-1 (Cytion catalog number 800100) or CM-ACF (Cytion catalog number 806100) |
Handling of cryopreserved cultures | NR8383 cells are shipped in a deep-frozen state on dry ice. Upon receipt, confirm that the vial remains frozen. For storage, place the cryovial immediately at temperatures below -150 degrees. If you plan to culture the cells immediately, swiftly thaw the vial by shaking it in a 37 degrees water bath with clean water and an antimicrobial agent for 40-60 seconds. Remove the vial once a small ice clump persists, ensuring it remains cold. Proceed with all subsequent steps under aseptic conditions. In a sterile flow hood, disinfect the cryovial with 70% ethanol. Then, gently open the vial and transfer the cell suspension into a 15 ml centrifuge tube pre-filled with 8 ml of room temperature culture medium. Gently mix the cells. For cell separation, centrifuge at 300 x g for 3 minutes and dispose of the supernatant. Skipping centrifugation is optional, although any residual freezing medium should be removed after 24 hours. Resuspend the pellet gently in 10 ml of fresh culture medium and divide between two T25 culture flasks. Follow the subculture protocol for subsequent steps. |
Quality control / Genetic profile / HLA
Sterility | Mycoplasma contamination is rigorously excluded using both PCR-based assays and luminescence-based mycoplasma detection methods. To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections. |
