Villin Antibody in Immunohistochemistry (Paraffin) (IHC (P)) — Immunohistochemical analysis of paraffin-embedded NCIN87 xenograft, using Villin (Product # PA5-29078) antibody at 1:500 dilution. Antigen Retrieval: Citrate buffer, pH 6.0, 15 min.

Villin Antibody in Western Blot (WB) — Western blot was performed using Anti-Villin Polyclonal Antibody (Product # PA5-29078) and a 92kDa band corresponding to Villin was observed across cell lines and tissues tested. Whole cell extracts (30 µg lysate) of Caco-2 (Lane 1), COLO 205 (Lane 2), HT-29 (Lane 3), Jurkat (Lane 4) and PANC-1 (Lane 5) as seen in Fig (a).Tissue extracts of Mouse Liver (Lane 1), Mouse Colon (Lane 2) and Mouse Jejunum (Lane 3) as seen in Fig (b) were electrophoresed using NuPAGE™ 4-12% Bis-Tris Protein Gel (Product # NP0321BOX). 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 (1:5000 dilution) and detected by chemiluminescence with Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).

Villin Antibody in Western Blot (WB) — Western Blot analysis of Villin was performed by separating 50 µg of Mouse tissue extracts by 7.5% SDS-PAGE. Proteins were transferred to a membrane and probed with a Villin Polyclonal Antibody (Product # PA5-29078) at a dilution of 1:1000. The HRP-conjugated anti-rabbit IgG antibody was used to detect the primary antibody.

Villin Antibody — Antibody specificity was demonstrated by detection of differential basal expression of the target across cell lines and tissues tested owing to their inherent genetic constitution. Relative expression of Villin was observed in High in Caco-2, COLO 205 and HT-29 as compared to low or negative in Jurkat and PANC-1 as seen in Fig (a),Similarly expression was observed high in Mouse Jejunum as compared to low or negative in Mouse Colon and Mouse Liver as seen in Fig (b) using Anti-Villin Polyclonal Antibody (Product # PA5-29078) in Western Blot.

Target Information

Villin is part of cytoskeleton associated with the microvillar actin core bundle of gastrointestinal and renal brush border. It can interact with actin in a Ca2+ and phosphoinositide-regulated manner. Villin is a very specific marker for adenocarcinomas of the gastrointestinal tract and the pancreas. It is also expressed in some Merkel cell tumor and adenocarcinoma of the lung, prostate, ovarian and kidney.
