Figure 1From: Ligand-dependent localization and intracellular stability of sigma-1 receptors in CHO-K1 cells Preadsorbtion control showing the specificity of the Anti-sigma-1 receptor antibody. CHO-K1 cells stained with anti-sigma1 antibody (0.6 μg/ml). A – no preadsorbtion; B – before immunostaining antibody was preadsorbed for 1 h with the purified sigma-1 protein (25 μg/ml).Back to article page
