检测方法

• MTT assay: Measures cell viability and proliferation using colorimetric analysis.
• LDH release assay: Detects cell membrane damage by quantifying lactate dehydrogenase leakage.
• ELISA: Quantifies cytokine levels through enzyme-linked immunosorbent assay.
• Flow cytometry: Analyzes immune cell populations and activation states using fluorescent labeling.
• Complement activation test: Assesses complement system response via hemolytic or ELISA-based methods.
• Hemolysis test: Evaluates red blood cell damage by measuring hemoglobin release.
• Skin sensitization test: Determines allergic potential using guinea pig maximization or local lymph node assays.
• Pyrogen test: Checks for fever-inducing substances via rabbit or in vitro monocyte activation tests.
• Ames test: Screens for mutagenicity using bacterial reverse mutation assay.
• Micronucleus test: Detects chromosomal damage in cells exposed to the product.
• Comet assay: Measures DNA strand breaks through single-cell gel electrophoresis.
• Western blot: Analyzes protein expression changes using antibody-based detection.
• PCR: Detects gene expression alterations via polymerase chain reaction.
• Histopathology: Examines tissue samples microscopically for toxicity signs.
• Immunohistochemistry: Localizes specific proteins in tissues using antibody staining.
• Animal models: Conducts in vivo testing for systemic toxicity in rodents or other species.
• Cell migration assay: Assesses immune cell movement using transwell or scratch methods.
