Cell culture is one of the major tools used in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells (e.g., metabolic studies, aging), the effects of drugs and toxic compounds on the cells, and mutagenesis and carcinogenesis. It is also used in drug screening and development. The major advantage of using cell culture for any of these applications is the consistency and reproducibility of results that can be obtained from using a batch of clonal cells. Cell Culture Plates (also generically called TC treated plates) offer optimal, uniform and compatible surface support for animal cell attachment and growth. This particular surface is obtained by proprietary vacuum plasma treatment, makes the polystyrene surface more hydrophilic, thus facilitating maximum adhesion for a broad range of cell types.
