Applications of 298-93-1
| Industry | Application | Process |
|---|---|---|
| Biopharmaceuticals | Cell viability assay (MTT method) | Add MTT (thiazolyl blue) to live cell cultures; mitochondrial dehydrogenases reduce yellow MTT to purple formazan crystals, which are dissolved in dimethyl sulfoxide (DMSO) and quantified by spectrophotometry at 570 nm to determine viable cell count. |
| Drug Discovery | Anticancer drug screening and efficacy evaluation | Perform MTT assay on in vitro cell models following co-treatment with test compounds to assess inhibition of cancer cell proliferation (IC50 determination). |
| Toxicology Research | Cellular toxicity assessment of chemical substances | Conduct MTT assay per OECD Test Guideline 429 to evaluate cytotoxicity of test substances against standard cell lines (e.g., L929, HEK293) and establish safe concentration ranges. |
| Basic Medical Research | Mechanistic studies of apoptosis, autophagy, and signaling pathways | Use as a live-cell quantitative reference to normalize cell number differences between experimental and control groups when combined with flow cytometry, Western blotting, and other techniques—enhancing reliability of mechanistic data. |
