Protein samples were collected from cell lysates using RIPA buffer (Beyotime, Beijing, China) when the cells reached over 80% confluence. Proteins (30 μg) were transferred onto polyvinylidene difluoride (Millipore, Boston, USA) membranes post-separation on 10% sodium dodecyl sulphate-polyacrylamide gel electrophoresis. Afterwards, the membranes were sealed with 5% skim milk in Tris Buffered Saline with Tween 20 (TBST) for 1 hour, followed by incubation with primary antibodies or GAPDH as a loading control at 4°C overnight. Subsequently, the membranes were rinsed 4 times with TBST and then incubated with secondary antibodies (Santa Cruz Biotechnology, Dallas, USA) on a slow shaker for 1 hour, followed by washing with TBST (5 times, 5 min/wash). The membranes were stained with ECL luminous liquid (GE Healthcare, Chicago, USA). The primary antibodies include anti-YAP1 (ab205270; Abcam, Cambridge, UK), anti-ankyrin repeat domain 1 (ANKRD1, ab272894; Abcam), anti-connective tissue growth factor (CTGF, ab209780; Abcam), and anti-GAPDH (ab8245; Abcam).

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.
