Alpha catenin

Manufactured by BD
Sourced in United States

Alpha-catenin is a cytoplasmic protein that plays a key role in the maintenance of cell-cell adhesion. It functions as a linker between the cadherin-catenin complex and the actin cytoskeleton, contributing to the stability of adherens junctions.

Protein Expression Analysis in Liver Tissue

Check if the same lab product or an alternative is used in the 5 most similar protocols
Liver tissues were homogenized on ice for 5 sec and then lysed in RIPA buffer containing 2 mM/ml Na3VO4 and 1x protease inhibitor cocktail (Sigma- Aldrich) for 20 min at 4°C. Whole tissue lysates were separated using SDS-PAGE and transferred onto a PVDF membranes. Primary antibodies used were Alpha-catenin (610194; BD Biosciences, San Jose, CA, USA), GAPDH (ab9485; Abcam), Yap (4912; Cell Signaling, Danvers, MA, USA) and phosphor-Yap-Ser127 (4911; Cell Signaling).

All analyses were performed as described previously [10 (link), 52 (link)]. For immunoblotting analysis, whole-cell lysates were made using a RIPA lysis buffer, resolved on Bis-Tris 10% gel, and transferred to PVDF membranes. The blots were then probed with various primary antibodies. E-cadherin, fibronectin, N-cadherin, alpha-catenin, and vimentin (BD Biosciences); Twist-1 and DJ-1 (Abcam); STAT3 and phospho-STAT3 (Cell Signaling Technology); HA and GFP (Santa Cruz Biotechnology); V5 (Life Technologies); β-actin (Sigma-Aldrich).
For Immunofluorescence staining, 1 × 104 cells were incubated with specific primary antibodies, washed, and then incubated with secondary antibodies (Invitrogen). Images were acquired using a confocal microscope LSM 700 (ZEISS).
For immunohistochemistry, a tissue microarray slide (CSA) was purchased from Super Bio Chips, and the expression of TrkC at the tissue microarray slide was evaluated by using an indicated antibody. In addition, the evaluation of immunostaining intensity was performed and obtained the score by ImageJ software.

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.
