Whole cell extracts (15 µg protein) from PC-3, HeLa, MOLT-4 (reduced expression control), and NIH/3T3 cells were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with 1.0 µg/mL (1:500 dilution) of purified anti-Vinculin antibody (clone W18245A) overnight at 4°C. Proteins were visualized by chemiluminescence detection using HRP goat anti-rat IgG antibody (Cat. No. 405405) at a 1:3000 dilution. Direct-Blot™ HRP anti-GAPDH antibody (Cat. No. 607904) was used as a loading control at a 1:25000 dilution (lower). Lane M: Molecular weight marker. Predicted VCL expression data was obtained from Human Protein Atlas.

    HeLa cells were fixed with 4% paraformaldehyde for 10 minutes, permeabilized with ice-cold methanol for 10 minutes, and blocked with 5% FBS for 60 minutes. Cells were then intracellularly stained with 5.0 µg/mL (1:100 dilution) of either purified rat IgG2a, κ isotype ctrl antibody (Cat. No. 400501) (panel A) or purified anti-Vinculin antibody (panel B) for two hours at room temperature, followed by incubation with Alexa Fluor™ 594 goat anti-rat IgG (Cat. No. 405422) at 2.0 µg/mL. Nuclei were counterstained with DAPI, and the image was captured with a 60X objective.

    Whole cell extracts (250 µg total protein) prepared from HeLa cells were immunoprecipitated overnight with 2.0 µg of purified rat IgG2a, κ isotype ctrl antibody (Cat. No. 400501) or purified anti-Vinculin antibody (clone W18245A). The resulting IP fractions and whole cell extract input (6%) were resolved by 4-12% Bis-Tris gel electrophoresis, transferred to a PVDF membrane, and probed with a rabbit control antibody raised against a separate epitope of Vinculin.

    IHC staining using purified anti-Vinculin (clone W18245A) on formalin-fixed paraffin-embedded human heart tissue. Following antigen retrieval using 1X Tris-Buffered Saline (final concentration 0.05M) with Tween-20 (Cat. No. 925501), the tissue was incubated with (B) or without (A) 10 μg/mL of antibody overnight at 4°C, followed by incubation with 2.5 μg/mL of Alexa Fluor® 647 goat anti-rat IgG (Cat. No. 405416) for one hour at room temperature. Nuclei were counterstained with DAPI (blue) (Cat. No. 422801), and the slide was mounted with ProLong™ Gold Antifade Mountant. The image was captured with a 40X objective. Scalebar = 50 μM

Description

Vinculin is a filamentous actin (F-actin) binding protein that was originally described as a critical component of focal adhesion plaques. It plays an important role in the transmission of mechanical forces, stabilization of cell-cell junctions via a direct interaction with α-catenin, and linking of integrins to the actin cytoskeleton. Loss of Vinculin protein expression contributes to metastatic phenotypes in cancer tissue due to loss of cell-cell adhesion. Vinculin has been isolated from prostate cancer exosomes and may serve as a biomarker for the progression of taxane-resistance prostate cancers; it is also a common marker for cell-cell and focal adhesion junctions.

Recommended Usage

Each lot of this antibody is quality control tested by western blotting. For western blotting, the suggested use of this reagent is 0.1 - 1.0 µg/mL. For immunocytochemistry, a concentration range of 1.0 - 5.0 μg/mL is recommended. For immunoprecipitation, the suggested use of this reagent is 2.0 µg/test. For immunohistochemistry on formalin-fixed paraffin-embedded tissue sections, a concentration range of 5.0 - 10.0 µg/mL is suggested. It is recommended that the reagent be titrated for optimal performance for each application.

Application Notes

This clone was tested for ICC using HeLa cells fixed with 4% PFA and permeabilized with Triton X-100 or methanol. While methanol permeabilization was compatible with Vinculin staining, Triton X-100 permeabilization resulted in dim staining. We therefore do not recommend Triton X-100 as a permeabilization method.

While this clone passed IP testing, it failed to quantitatively enrich Vinculin from whole cell extracts and may not be suitable for detecting transient or low-abundance protein-protein interactions by co-immunoprecipitation.

This clone is predicted to recognize Metavinculin due to complete sequence homology between the immunogen and the corresponding region of Metavinculin.
