Cell Culture
Cell Culture — The process of growing and maintaining cells under controlled conditions outside their natural environment, a primary method for in vitro peptide research.
What Is Cell Culture?
Cell culture grows and maintains cells in vitro under controlled conditions. It is the primary system for evaluating peptide biological activity before in vivo studies.
Cell Culture Types
- Primary cells: Freshly isolated from tissue. Most physiologically relevant but limited lifespan
- Immortalized lines: Indefinite growth (HEK293, CHO, HeLa). Consistent and reproducible
- Reporter lines: Engineered readouts (luciferase, GFP) for dose-response studies
- 3D cultures: Spheroids, organoids provide more physiological architecture
Peptide Considerations
Use endotoxin-tested peptides (LPS causes false inflammatory responses). Account for peptide adsorption to plastic surfaces. Verify bacteriostatic water benzyl alcohol does not affect viability at the final dilution.
