Figure S2 -Comparison of different lysis buffers in extraction of Cx43 proteins from HAEC treated with a serious concentrations of AGE-BSA, as detected by Western blotting. No differences on the expression levels of Cx43 protein were detected using both extraction buffers. Note that no difference in decreasing trends or patterns of Cx43 proteins extracted from cells using either NP40 (A) or SDS (B) buffers.
