N cadherin

Manufactured by Abcepta
Sourced in United States

N-cadherin is a type of cell adhesion molecule that plays a crucial role in the formation and maintenance of tissues and organs. It is a transmembrane protein that facilitates the adhesion between cells, allowing them to communicate and coordinate their activities. N-cadherin is essential for the development and function of various tissues, including the nervous system, cardiovascular system, and musculoskeletal system.

Equal amounts of whole-cell lysate were loaded onto a 10% or 12% sodium dodecyl sulfate-polyacrylamide gel and assayed by enhancing the chemiluminescence as described by the manufacturer (PerkinElmer Inc., Waltham, MA, USA). The blotting membranes were probed with antiserum of NIK, IĸBα, Akt, phospho-AktS473, Slug (Cell Signaling Technology, Danvers, MA, USA), MMP9, Snail (Abcam, Cambridge, MA, USA), MIEN1 (OriGene Technologies), NDRG1 (Invitrogen Thermo Fisher Scientific Inc., Waltham, MA, USA), E-cadherin (Santa Cruz Biotechnology, Santa Cruz, CA, USA), N-cadherin (Abgent, San Diego, CA, USA), or β-actin (Merck Millipore, Burlington, MA, USA). The intensities of different bands were analyzed using the GeneTools of ChemiGenius (Syngene, Cambridge, UK).

Cells were lysed in RIPA buffer (50 mM Tris-Cl at pH 7.5, 150 mM NaCl, 1% NP-40, 0.5% sodium deoxycholate, 1 mM EDTA, 1 μg/mL leupeptin, 1 μg/mL aprotinin, 0.2 mM PMSF) and proteins (20–40 μg) were separated on 8–10% SDS/PAGE gel and then transferred onto PVDF membranes (Millipore, Billerica, MA). After blocking procedure, membranes were incubated with primary antibodies (1:1000), HRP-conjugated secondary antibodies (1:5000), and visualized in Imager (Bio-Rad) using ECL system (Thermo Fisher Scientific, Rochester, NY). Antibodies of ATM, p-ATM, JAK1, p-JAK1, JAK2, p-JAK2, STAT3, and p-STAT3, were from Gene Tex (Irvine, CA), Antibodies of E-cadherin, N-cadherin, Vimentin, Snail, Zeb1, Twist and VEGF were obtained from Abgent (San Diego, CA) and antibodies of PD-L1, GAPDH, were from Cell Signaling (Danvers, MA).

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.
