Human Lung Cancer-Associated Fibroblasts (CAFs) Product Specifications
Quality Control & Characterization
Our Human Lung CAFs undergo rigorous testing to ensure research-grade quality. The cells demonstrate negative expression of endothelial (von Willebrand Factor/Factor VIII), epithelial (cytokeratin 18), and smooth muscle (α-SMA) markers, confirming fibroblast purity. All cultures are certified free from microbial contamination (bacteria, yeast, fungi, and mycoplasma). The cells positively express characteristic CAF markers including FAP, PDGFR, Vimentin, PDPN, and CD70, and maintain stable growth for 3-5 passages when subcultured at a 1:2 to 1:3 ratio.
Research Applications
These primary lung CAFs are suitable for:
• Tumor microenvironment interaction studies
• Cell adhesion and migration assays
• Molecular analysis (PCR, Western blot, immunoprecipitation)
• Cellular characterization (immunofluorescence, flow cytometry)
• Development of advanced cancer models
Cell Handling Protocol
Shipping & Storage
Delivered frozen on dry ice
For optimal results:
Immediate culture initiation recommended
Alternative storage: liquid nitrogen vapor phase
Avoid -70°C storage (compromises cell viability)
Thawing & Culture Initiation
Rapidly thaw cells in 37°C water bath (2 minutes maximum)
Sterilize vial exterior with 70% ethanol
Remove cryoprotectant via centrifugation (125 × g, 5-10 min)
Resuspend in fresh CAF Growth Medium
Plate in AlphaBioCoat-precoated T75 flask (6-8 mL coating solution, 15 min)
Maintain at 37°C with 5% CO₂ (pre-equilibrate medium 15 min before use)
Subculture Procedure
Aspirate spent medium and rinse with PBS
Add 2-3 mL Cell Detachment Solution (5-15 min incubation)
Neutralize with complete medium (6-8 mL)
Replate at recommended split ratio (1:2 to 1:3) in freshly coated flasks
Perform medium changes every 3-4 days
Cryopreservation
Use complete growth medium with 5% DMSO
Store long-term in liquid nitrogen vapor phase
