SNU1196 and HUCCT1 cells (2 × 105 cells/well) were plated into a 96-well plate 24 h before incubation with media containing viral particles overnight at 37 °C. The media were removed and replaced with fresh culture media, and puromycin (2 mg/mL) was used to select stable AXL knockdown cells, which was confirmed by Western blotting. For GAS6 stimulation, cells were kept in serum-free medium for 24 h and then treated with 10 μg/mL or 100 μg/mL AVB-500 with the addition of 50 ng/mL GAS6 (R&D systems #885-GSB-050) for 24 h.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
