WebJun 21, 2011 · Copper is an essential micronutrient for all organisms because it serves as a cofactor of several proteins involved in electron transfer. Elevated copper concentrations can cause toxic effects and organisms have established suitable mechanisms to regulate the uptake and internal distribution of copper to balance the content at an optimal … WebCopper is an essential element in cell culture. However, classical media do not typically contain it in their basal formulations. This is likely because sera used at 5 to 10% provides sufficient copper for cell growth and survival, approx. 50 to 100 ng/mL. Efforts to develop serum-free media necessitate the addition of copper to the cell ...
