Why is it important to do endotoxin and hybridoma testing in animal cell culture products like DMSO and media?

In animal cell culture, the requirements for the cell are only those that are beneficial to the cell and which do not cause any harm to the normal physiological activities of the cell. Endotoxins can hamper normal activities of cell and can even lead to cell death. Hybridomas can out-compete the cultured cells for nutrients. Thus, both reduce the activity of the cultured cells. This is why is it important to do testing of cell culture products so that there is no addition of such substances detrimental to the cell.


Why is DMSO used as a control?

Many test compounds (drugs, inhibitors, etc) are not soluble in water and therefore dimethylsulfoxide (DMSO) is used as a solvent instead. The compound dissolved in DMSO is what is used to treat the cell or animal and therefore you must prove that it is the compound, not the DMSO which is causing any results seen. To ensure this, you have a control that contains only DMSO and not the test compound. This is often referred to as a "vehicle control".
