Quality-Controlled Human Bronchial CAFs for Cancer Research
Cell Authentication & Safety Testing
Our Human Bronchial Cancer-Associated Fibroblasts (CAFs) undergo comprehensive quality control to ensure research reliability. The cells test negative for endothelial (von Willebrand Factor/Factor VIII), epithelial (cytokeratin 18), and smooth muscle (α-SMA) contamination, confirming fibroblast purity. All cultures are certified free from bacteria, yeast, fungi, and mycoplasma contamination. These CAFs maintain optimal growth characteristics for 3-5 passages when subcultured at a 1:2 to 1:3 split ratio.
Research Applications
These primary bronchial CAFs are ideal for:
Tumor microenvironment interaction studies
Cell adhesion and migration assays
Molecular biology techniques (PCR, Western blot, IP)
Cellular characterization (immunofluorescence, flow cytometry)
Development of specialized cancer models
Cell Handling Protocol
Shipping & Storage
Shipped frozen on dry ice
For best results:
Immediate culture initiation recommended
Alternative storage: liquid nitrogen vapor phase
Avoid -70°C storage (reduces viability)
Thawing & Culture Initiation
Rapidly thaw cells in 37°C water bath (~2 min)
Decontaminate vial with 70% ethanol
Remove cryoprotectant by centrifugation (125 × g, 5-10 min)
Resuspend in fresh CAF Growth Medium
Plate in AlphaBioCoat-coated T75 flask (6-8 mL, 15 min coating)
Maintain at 37°C, 5% CO₂ (pre-equilibrate medium 15 min)
Subculture Procedure
Remove spent medium and rinse with PBS
Add 2-3 mL Cell Detachment Solution (5-15 min, 37°C if needed)
Neutralize with complete medium (6-8 mL)
Replate at 1:2 to 1:3 ratio in freshly coated flasks
Refresh medium every 3-4 days
Cryopreservation
Use complete growth medium with 5% DMSO
Store in liquid nitrogen vapor phase for long-term preservation
