ImmunofluorescenceHeLa cells were fixed and permeabilized with 1% paraformaldehyde in a buffer containing 10 mM MES pH 6.2, 10 mM NaCl, 1.5 mM MgCl
2 and 2.5% glycerol and subsequently permeabilized with 0.1% Triton
™ X-100. Fixed cells were co-immunostained with 2 μg Rabbit Anti-COG5 (
Cat. No. SAB4200440) followed by Goat Anti-Rabbit IgG, Cy3
™ conjugate (red, panel A and B) and with a Golgi marker (green, panel B). Cells were counterstained with DAPI to stain nuclei (blue, panel B). The pictures are courtesy of Dr. Orly Laufman and Prof. Sima Lev, Dept. of Molecular Cell Biology, Weizmann institute of Science, Rehovot, Israel.
ImmunoblottingWhole extract of HEK-293T cells overexpressing human COG5 cells was separated on SDS-PAGE and probed with Rabbit Anti-COG5 (
Cat. No. SAB4200440). The antibody was developed using Goat Anti-Rabbit IgG-Peroxidase (
Cat. No. A0545) and a chemiluminescent substrate.
