Figure 2. Low temperature exposure increases the protein expression levels of hKv1.5.

Western blot analysis of the total membrane proteins extracted from the CHO-hKv1.5s cells (left panel) or native CHO cells (NC, as a negative control) cultured at 37°C or 28°C for 48 h. The specificity of the hKv1.5 antibody was characterized by an antigen absorption test. GADPH was used as control for protein loading.
