Fixing cells with methanol
WebRetinal capillary endothelial cells (RCECs) were treated with high-glucose and high-lipid (HG/HL) culture medium, and siRNA transfection to investigate the role of PDLIM1 in DR. PDLIM1 and Wnt3a expression was confirmed by qRT-PCR and western blotting. WebMethanol and other organic solvents dissolve lipids from the cell membranes making the permeable for antibody staining. They can also be used to fix cells simultaneously. However,...

WebThe relatively low-price methanol has been considered a promising energy source for CO 2 assimilation. To produce the required energy for CO 2 fixation, methanol is initially oxidized in the peroxisome of P. pastoris to hydrogen peroxide (H 2 O 2), which may lead to oxidative damage to cells, and the toxic formaldehyde 48.
