Fig. 9From: The adverse vascular effects of multi-walled carbon nanotubes (MWCNTs) to human vein endothelial cells (HUVECs) in vitro: role of length of MWCNTsThe protein level of BiP (GRP78) in human umbilical vein endothelial cells (HUVECs) after exposure to XFM22 (the shorter MWCNT) and XFM19 (the longer MWCNT). HUVECs were exposed to 0 or 32 μg/mL XFM22 and XFM19 for 24 h, and Western blot was used to determine the protein level of BiP with α-Tubulin as the internal controlBack to article page
