CHO

Description: Chinese Hamster Ovary Cells

Edit - History

Introduction

CHO cells are a line of epithelial-like cells that was initiated in 1957 by T.T. Puck and colleagues at the Department of Biophysics, University of Colorado Medical School in Denver, USA from a biopsy of an ovary of an adult Chinese hamster [1352]. There are several specific features that make the CHOcell line one of the most convenient solutions for reconstitution of mammalian ionchannels and related proteins: 1) it is a mammalian cell line; 2) they are adherent cells that make them easier to transfect compared to cell lines that grow in suspension; 3) cells are not electrotonically coupled and so are easy to voltage clamp, and 4) they express very little endogenous currents.
