Cytotoxicity Assay Service

The purpose of developing a cytotoxicity test is to analyze the ability of certain pharmaceutical compounds to destroy healthy cells in an organism. Cytotoxic compounds can cause accidental cell death or programmed cell death. In the non-clinical and clinical research phases of drug discovery and development, cytotoxicity tests evaluate the safety of candidate drugs. This method proves to be valuable in identifying the off-target effects of certain pharmaceutical compounds on the human body. For pharmaceutical compounds developed for cancer treatment, cytotoxicity determination is crucial in various assay activities. Compounds that can hinder or prevent cell proliferation are powerful anti-cancer candidates. CD BioSciences can provide you with professional cytotoxicity assay service to meet the specific needs of different customers.

Overall solution

The cytotoxicity assay provided by CD BioSciences can be used to evaluate different cell functions, such as cell membrane permeability, enzyme activity, ATP production, cell adhesion, nucleotide uptake and coenzyme production. CD BioSciences will select the cytotoxicity test based on the drug compound and carefully consider the cell function.

Quantitative Assays

Luciferase-ATP Assay – Cell viability is an alternate readout for cytotoxicity. Luciferase is a commonly used enzyme that converts luciferin to oxyluciferin in the presence of ATP. ATP is found in viable cells and is proportional to the number of viable cells present. This assay is adaptable to high-throughput formats. It is also a sensitive readout of cytotoxicity in a variety of cells.

MTT Assay – The MTT cytotoxicity assay uses 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide dye, commonly referred to as MTT. The conversion of MTT to formazan only occurs in viable cells.

Qualitative Assays

Qualitative assays, such as the MEM elution assay, direct contact test, and agar diffusion test are used infrequently. In these assays, cells are exposed to a drug or compound, and cell deformity is assessed visually, on a predetermined scale.
