• Cell Lines, Primary Cultures

    Posted on Nov 15, 2018

    Cell lines maintain growth and specialized properties during prolonged or indefinite culture in the laboratory. Primary cell isolates are derived fresh from tissues and will grow and maintain specialized properties for a limited time, about 10 passages. Marin Biologic has experience with explants of liver, breast, ovary, lung, skin, spleen, lymph node and brain. Both cell lines and primary cultures can be stored frozen in liquid nitrogen and then put back into culture. These methods facilitate biological studies that are convenient, reproducible, and cost effective. Cell lines allow studies that may be difficult with whole organs or in vivo. These studies include mechanism of action, radioactive experiments, or system manipulation. Cell lines with desired properties are obtained from repositories such as the American Type Culture Collection (ATCC) or derived by Marin Biologic through selection techniques and/or DNA transfection (see below).
