Cell Proliferation
Cell Proliferation — The process of cell growth and division, frequently measured as an endpoint in peptide bioactivity assays using MTT or BrdU methods.
What Is Cell Proliferation?
Cell proliferation is the increase in cell number through division. Proliferation assays measure whether a peptide stimulates (mitogenic) or inhibits (antiproliferative) cell growth. These assays are fundamental for characterizing growth factor-mimetic peptides, anti-cancer peptides, and establishing non-cytotoxic concentration ranges for all research peptides.
Proliferation Assays
- BrdU incorporation: Thymidine analog incorporated into DNA during S-phase. Detected by anti-BrdU antibody
- Ki-67 staining: Nuclear protein present only in proliferating cells
- Cell counting: Direct count by hemocytometer or automated counter over time
- WST-1/MTS: Colorimetric assay correlating metabolic activity with cell number
Frequently Asked Questions
