It provides a far better description of the cytotoxicity of an agent in a specific cell line than the traditional LC50. The concentration at which k2 is reduced by 50% is called KC50.
Many substances have a toxic effect. Some are more toxic than others, and it is vital that scientists and medical professionals know the effects and how severely they can affect an organism. Toxicity is defined as the quality a substance (for example, a drug) has of being toxic or poisonous. Toxicity is dependent on … See more Whilst cytotoxicity can be measured in several ways, the most common methods are measuring ATP content, using protease markers, or using vital dyes such as formazan dyes. Most cytotoxic assays work on the premise … See more One field that cytotoxicity measurement plays a part in is cancer research and chemotherapy drugs.
