1mM EDTA, 1% Triton X-100, 0.5% Sodium deoxycholate, protease and phosphatase
inhibitors]. Proteins were separated by SDS-PAGE and transferred onto
nitrocellulose membranes. Blocking and antibody incubations were performed in 5%
BSA. Myosin light chain 2 (MLC2) (Cat#:3672, 1:1000 dilution), phospho-MLC2
(Ser19) (Cat#:3671, 1:1000 dilution), COFILIN (Cat#:5175, 1:1000 dilution) and
phospho-COFILIN (Cat#:3311, 1:1000 dilution) antibodies were purchased from Cell
Signaling; beta-ACTIN (Sigma-Aldrich, Cat#:A5441, 1:1000 dilution) antibody
detection was used as loading control. Antibody detection reactions were
developed by enhanced chemiluminescence (Advansta) and imaged using the c300
imaging system (Azure Biosystems). Quantification was done using ImageJ
software.
