- Description
- Description: The monoclonal antibody 20C8 recognizes human Snail1, a 29 kDa zinc finger transcription factor. Snail1 and Slug both belong to a family of transcription factors that are responsible for inducing epithelial to mesenchymal transition (EMT) during normal organ development and tumor progression. Snail1 expression is localized to both the cytoplasm and nucleus and functions as a transcriptional repressor of E-cadherin, claudins, occludin, and desmoplakin. During embryonic development, Snail1 is localized to the mesoderm, while in the adult, expression is inducible and is usually limited to activated fibroblasts and some mesenchymal cells. Overexpression of Snail1 has been found in carcinomas and fibrosarcomas and may be used as an early marker for EMT. Applications Reported: This 20C8 antibody has been reported for use in immunohistochemical staining of formalin-fixed paraffin embedded (IHC-P) tissue, ELISA, immunoprecipitation, western blotting, and immunocytochemistry. Applications Tested: This 20C8 antibody has been tested by immunohistochemistry on formalin-fixed paraffin embedded (FFPE) human breast cancer tissue using low pH antigen retrieval. The antibody can also be used following high pH antigen retrieval. This antibody can be used at less than or equal to 5 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Purity: Greater than 90%, as determined by SDS-PAGE. Aggregation: Less than 10%, as determined by HPLC. Filtration: 0.2 µm post-manufacturing filtered.

- Western blot was performed using Anti-SNAIL polyclonal Antibody (Product # 14-9859-82) and 29 kDa band was observed corresponding to SNAIL was observed across the cell lines tested and increased upon LPS treatment in MCF7. Whole cell extracts (30ug lysate) of MCF-7 (Lane 1), MCF-7 treated LPS (5ug/ml for 48hrs) (Lane 2) and MDA-MB-231 (Lane 3) were electrophoresed using Novex® NuPAGE® 4-12 % Bis-Tris gel (Product # NP0322BOX). Resolved proteins were then transferred onto a nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1ug/ml) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Secondary Antibody, HRP (Product # A28177) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005)(https://doi.org/10.3892/or.2012.2080).
