OFTu cells mock-infected or infected with OV-SY17 (MOI = 1) and treated with different concentrations of genistein (0 μM, 10 μM, 50 μM, and 100 μM) were collected, washed twice with PBS, and then lysed on ice for 30 min using RIPA lysis buffer (Beyotime, China) containing 1% protease inhibitors. Protein samples were subjected to quantification by a BCA assay (Beyotime, China) prior to Western blot analysis. The equal amounts of protein samples were resolved by SDS-PAGE on 10% gels and then transferred to a PVDF membrane (Millpore, United States). The membranes were blocked in 5% non-fat milk and incubated overnight at 4°C with primary antibodies, such as ORFV059 polyclonal antibody (prepared in our laboratory) or β-actin monoclonal antibody (Proteintech, China). Subsequently, the membranes were incubated with appropriate secondary antibodies. Protein bands were visualized using ECL Western blotting detection reagents. The results were normalized to those for β-actin.

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.
