U2OS cells were fixed with 4% paraformaldehyde for 20 minutes, followed by blocking with 5% goat serum for 1 hour. The cells were then incubated with a primary antibody targeting CSPG4 (HV349014) at a concentration of 28 ug/ml overnight at 4°C. Afterward, the cells were incubated with a secondary antibody, Goat Anti-Rabbit IgG (Alexa Fluor-488) for 50 minutes at room temperature. The localization of CSPG4 was visualized (shown in green), and nuclear DNA was stained with DAPI (shown in blue).
