Cytoxicity
Cytotoxicity describes the property of a substance that being toxic to cells.
| MTT colorimetric cell viability assay | L929 cells |
| Neutral Red colorimetric cell viability Assay | 3T3 cells |
Genotoxicity
Genotoxicity describes the property of a substance that damages the genetic information within a cell.
| Micronucleus assay | TK6 cells |
| Postural hypotension (telemetry) | Rat |
Irritation
Cardiac activity, including electrical activity, is monitored under different conditions.
| Reconstituted human epidermis irritation assay | Episkin |
| HET-CAM (Hen’s Egg Test Chorio Allantoic Membrane) - alternative to occular irritation assay | Chicken egg |
| Acute dermal irritation (topical application) | Rabbit |
| Intradermal reactivity test (intracutaneous injection) | Rabbit |
| Skin irritation test | Rabbit |
Skin Sensitization
Skin sensitization is the identification of chemicals able to elicit an allergic response.
| Guinea-pig Maximization Test (GPMT) | Guinea-pig |
| Local Lymph Nodes Assay (LLNA) | Mouse |
Toxicity
Toxicity is the degree to which a chemical substance or a particular mixture of substances can cause damage.
| Acute systemic toxicity (or repeated doses) alternative to embryotoxicity in mammals | Chicken egg |
| Acute systemic toxicity | Mouse - Rat |
| Repeated doses systemic toxicity | Mouse - Rat |
