A cell culture assay is any method used to assess the cytotoxicity of a material. [1] [2] This refers to the in vitro assessment of a material to determine whether it releases toxic chemicals in the cell. It also determines if the quantity is sufficient to kill cells, either directly or indirectly, through the inhibition of cell metabolic pathways.
In vitro toxicity testing is the scientific analysis of the toxic effects of chemical substances on cultured bacteria or mammalian cells. [1] In vitro (literally 'in glass') testing methods are employed primarily to identify potentially hazardous chemicals and/or to confirm the lack of certain toxic properties in the early stages of the development of potentially useful new substances such as ...
Label-free real-time techniques provide the kinetics of the cytotoxic response rather than just a snapshot like many colorimetric endpoint assays. Material that has been determined as cytotoxic, typically biomedical waste , is often marked with a symbol that consists of a capital letter "C" inside a triangle.

A cell rounding assay (cytotoxicity assay) has been developed to diagnose C. difficile infection. [11] Enzyme-linked immunosorbent assays (ELISAs) have been used to detect TcdA and TcdB with specific antibodies. When used with an ELISA, the cytotoxicity assay is the "gold standard" when used on Vero cells for C. difficile diagnosis. [11]
[2] [3] The cell culture assay is regarded as a "gold standard" for detecting toxicity in C. difficile because a small quantity of toxin B is capable of causing cell rounding (Fig. 4), thus, it is a major advantage of clinical laboratories to make correlations with the CDAD caused by TcdB.
Complement-dependent cytotoxicity (CDC) is an effector function of IgG and IgM antibodies.When they are bound to surface antigen on target cell (e.g. bacterial or viral infected cell), the classical complement pathway is triggered by bonding protein C1q to these antibodies, resulting in formation of a membrane attack complex (MAC) and target cell lysis.
K i is the inhibition constant for a drug; the concentration of competing ligand in a competition assay which would occupy 50% of the receptors if no ligand were present. [ 5 ] The Cheng-Prusoff equation produces good estimates at high agonist concentrations, but over- or under-estimates K i at low agonist concentrations.
