Rabbit anti human e cadherin antibody

Manufactured by Cell Signaling Technology
Sourced in United States, China, Japan

The Rabbit anti-human E-cadherin antibody is a primary antibody that specifically binds to the E-cadherin protein expressed in human cells. E-cadherin is a key cell-cell adhesion molecule involved in the maintenance of epithelial cell-cell junctions and tissue integrity. This antibody can be used to detect and study the expression and localization of E-cadherin in various human cell and tissue samples.

The primary antibodies were rabbit anti-human E-cadherin antibody (#3195; 1:1,000) and rabbit anti-human β-actin antibody (#4967; 1:1,000) (both from Cell Signaling Technology, Beverly, MA, USA). Horseradish peroxidase-conjugated (HRP) anti-rabbit antibodies (1:5,000; Santa Cruz Biotechnology, Santa Cruz, CA, USA) were used as the secondary antibodies. Cell lysates in 1X SDS loading buffer (60 mM Tris-HCl, pH 6.8; 2% SDS; 20% glycerol; 0.25% bromophenol blue; and 1.25% 2-mercaptoethanol) were incubated at 100°C for 10 min to facilitate sample loading for conventional western blot analysis. The relative protein levels were quantified using densitometry with a Gel-Pro Analyzer (Media Cybernetics, Rockville, MD, USA).

The construction of TMAs and immunohistochemistry were performed as previously described.22 (link) Rabbit anti-human UHRF2 monoclonal antibody (1:1,000; Wuhan Boster Biological Technology, Ltd., Wuhan, People’s Republic of China) and rabbit anti-human E-cadherin antibody (1:100; Cell Signaling Technology, Danvers, MA, USA) were utilized to detect the levels of UHRF2 and E-cadherin. The density level of strong, moderate, and weak staining was defined as in previous studies.22 (link)–24 (link) The assessment was performed blindly by two pathologists.

The whole cell lysates were prepared with RIPA buffer (Thermo Scientific) with a protease inhibitor mixture (Sigma), and the nuclear proteins were isolated with NE-PER Nuclear and Cytoplasmic Extraction Reagents (Thermo Scientific) as reported previously [19] . The protein concentration was determined by using a DC Protein Assay (Bio-Rad). The lysates (20 μg) were separated by electrophoresis on SDS-PAGE gels and transferred electrophoretically onto nitrocellulose membranes according to our previous reports [25] [26] [27] [28] . The following primary antibodies (Cell Signaling Japan, Tokyo, Japan) were used: rabbit anti-human E-cadherin antibody, rabbit anti-human N-cadherin antibody, rabbit anti-human vimentin antibody, rabbit anti-human ZEB1 antibody, rabbit anti-human ZEB2 antibody, rabbit anti-human β-actin antibody, rabbit anti-human histone H3 antibody, and rabbit anti-human α-tubulin antibody. After the reaction with a proper secondary antibody labeled with horseradish peroxidase (Cell Signaling Japan), the peroxidase activity was detected with an enhanced chemiluminescence detection system (GE Healthcare).

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.
