Figure 2From: Ligand-dependent localization and intracellular stability of sigma-1 receptors in CHO-K1 cells In CHO-K1 cells during a 30 sec rinsing with buffers with or w/o Ca 2+ and Mg 2+ before fixation changed the intracellular distribution of endogenous sigma-1 receptors. A. Cells were rinsed with DPBS w/o Ca2+ and Mg2+ and DMEM. B. Cells were rinsed with DPBS with different concentrations of Ca2+ and Mg2+ Back to article page
