KMD Bioscience has been committed to cell biology technology research for many years, based on advanced technical equipment and complete platform construction, we can provide customers with cell proliferation/toxicity detection services. KMD Bioscience has experienced technicians who have been engaged in cell proliferation/toxicity testing for many years, and can analyze cell proliferation or cytotoxicity with high efficiency.

KMD Bioscience has established a complete cell culture platform with complete detection and analysis equipment related to animal experiments, and we can provide customers with a variety of cytology basic experiments. Relying on our own laboratory, we can undertake all kinds of cell proliferation/toxicity detection, and can provide a full set of customized technical services from cell culture, cell processing and production, image collection, data measurement and so on.

Cell proliferation is an important vital feature of an organism, and cells multiply in a dividing manner. Cell proliferation refers to the process by which cells grow and divide into two daughter cells and is an important life feature of an organism. Through division, the copied genetic material can be evenly distributed into two daughter cells, which is the basis for the growth, development, reproduction and inheritance of organisms. Single-celled organisms, which produce new individuals in the way that cells divide. Multicellular organisms, which produce new cells in the form of cell division to replenish aging and dying cells in the body; At the same time, multicellular organisms can be made from a fertilized egg, which undergoes cell division and differentiation and eventually develops into a new multicellular individual. Cell proliferation detection can indicate the proliferative activity of tumor cells, cell proliferation activity of transient/stable cell lines of target genes, and plays an important role in the screening and functional safety of small molecule compounds/peptides, the screening and functional safety of traditional Chinese medicines/intermediates and other medcine, the gene function of target gene overexpression, and the gene function of target gene RNAi interference.

Cytotoxicity is a simple cell-killing event caused by synthetic compounds, naturally occurring toxicity of cells, or immunomodulatory cells (e.g., cytotoxic T lymphocytes, natural killer cells, etc.). Unlike apoptosis and necrosis, cytotoxicity does not refer to a specific mechanism of cell death and does not depend on the mechanism of cell death of apoptosis or necrosis. Cytotoxicity analysis can be used in basic research and medcine discovery to screen toxic compound libraries. Compounds that produce cytotoxic reactions can be eliminated in subsequent screening; Alternatively, compounds targeting rapidly dividing cells can be selected as candidates for cancer therapy.

There are many commonly used cell proliferation/toxicity detection technologies, and Camed Bio uses MTT and CCK-8 to provide cell proliferation and toxicity detection services for customers. 

Cell Proliferation/Toxicity Testing Services — MTT Method:

Dimethylthiazole diphenyltetrazolium bromide salt (MTT), light yellow powder, good water solubility. It can be taken up by various living cells (except red blood cells), and reduced by succinate dehydrogenase in the mitochondria, transforming from a yellow soluble solution into insoluble blue-violet crystalline formazan particles. Under normal circumstances, dead cells do not have this function. The cells are lysed with a certain lysate and the formazan is dissolved, and the degree of cell proliferation can be inferred by measuring the absorbance value of the solution. The MTT method is simple, fast and accurate, and is a method often used in cytotoxicity tests and cell proliferation experiments.

Cell Proliferation/Toxicity Testing Services — CCK-8 Method:

CCK-8 (Cell Counting kit-8) reagent contains WST-8 [its chemical name: 2-(2-methoxy-4-nitrophenyl) -3-(4-nitrophenyl) -5- (2,4-disulfonic acid benzene) -2H-tetrazolium monosodium salt], which is reduced by dehydrogenase in cells to a highly water-soluble yellow formazan dye, and the number of formazan products generated is proportional to the number of viable cells. At a wavelength of 450 nm ~ 490 nm, The absorbance is determined by microplate reader, and the higher the OD value, the higher the number of viable cells, and the stronger the cell proliferation ability of the test product. Procedure of CCK-8 assay: cell seeding→ cell culture→ addition of CCK-8 reagent→ incubation → determination of absorbance. This method allows direct cell proliferation and toxicity analysis.
