Transport and intracellular distribution of copper in a human hepatoblastoma cell line, HepG2
Richard J. Stockert, Phyllis S. Grushoff, Anatol G. Morell, Glenn E. Bentley, Harold A. O'Brien, I. Herbert Scheinberg, Irmin Sternlieb – 1 January 1986 – The uptake of radiocopper by HepG2 cells is a saturable, temperature‐dependent and cellular energy‐independent process with a Vmax of 7.1 ± 0.2 pmoles min−1 mg protein−1 andan estimated Km of 3.3 ± 0.5 μM. The rate of copper uptake is reduced at an equimolar concentrationof albumin and is unaffected by zinc at a 10‐fold molar excess.
