Cell culture media is a nutrient-rich solution designed to support the growth and maintenance of cells outside their natural environment, commonly used in research, biotechnology, and pharmaceutical production. It contains essential components such as amino acids, carbohydrates, vitamins, salts, and sometimes serum, which provide the necessary nutrients and growth factors. The media also includes buffers to maintain optimal pH levels, ensuring a stable environment for cell proliferation and differentiation. Different formulations of cell culture media are tailored to specific cell types and applications, making it a critical tool in biological sciences.
