Anti yap taz

Manufactured by Cell Signaling Technology
Sourced in United States

Anti-YAP/TAZ is a laboratory reagent that can be used to detect and quantify the expression levels of the YAP and TAZ proteins in biological samples. YAP and TAZ are transcriptional co-activators that play key roles in the Hippo signaling pathway, which regulates cell growth, proliferation, and survival. Anti-YAP/TAZ can be used in various research applications, such as Western blotting, immunohistochemistry, and immunocytochemistry, to investigate the involvement of YAP and TAZ in various cellular processes and disease states.

The treated cells were collected in RIPA buffer (Sigma, MO, USA). Nuclear and cytoplasmic protein extractions were prepared using NE-PER nuclear and cytoplasmic extraction kit (Thermo Scientific, MA, USA) following manufacturer’s instructions. Total protein content was measured by DC protein assay (Bio-Rad, CA, USA). The extracted proteins (20 μg) were then resolved on 10% SDS-PAGE and transferred to PVDF membrane. The membrane was then blocked with 5% skim milk or BSA, followed by overnight incubation with primary antibodies, anti-YAP/TAZ, anti-YAP (D8H1X), anti-Phospho-YAP1 (Ser127), anti-CCND1 and anti-GADPH (Cell Signaling, MA, USA), anti-GPER, anti-ERa and anti-Ki67 (Abcam, CA, USA), and anti-b-actin (Invitrogen, CA, USA) at 1:1000 dilution. After washing, the blots were incubated with goat anti-rabbit IgG (H + L)-HRP conjugate or goat anti-rabbit IgG (H + L)-HRP conjugate (Bio-rad, CA, USA). The protein bands were visualized with enhanced chemiluminescence reagent (Clarity Western ECL Substrate, Bio-Rad, CA, USA). GADPH and b-actin served as loading control.

Protein extraction, SDS-PAGE, and Western blot were performed as previously described [6 (link)]. Briefly, 40–60 μg of protein was separated by SDS-PAGE, electrophoretically transferred to PVDF membranes, blocked with 5% milk in TBS (50 mM Tris-HCl, pH 7.6; 150 mM NaCl), and probed overnight at 4 °C with the following antibodies: anti-YAP/TAZ (8418, Cell Signaling, Danvers, MA, USA), anti-Fibronectin (F3648, Sigma-Aldrich, St. Louis, MO, USA), and anti-GAPDH (sc-365062, Santa Cruz Biotechnology, Santa Cruz, CA, USA).

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.
