Fig. 2. Abundance of MARCKS and CaM in smooth muscle. (A) MARCKS immunoblot of whole-cell homogenate of portal vein. (B) Quantitation of portal-vein MARCKS immunoblot, protein matched for total cellular protein compared with a standard curve generated for calf-forebrain homogenates. (C) CaM immunoblot of whole-cell homogenate of portal vein. (D) Quantitation of portal-vein CaM immunoblots protein matched for total cellular protein compared with a standard curve generated by calf-forebrain homogenates.
