Mouse anti vinculin hvin 1

Manufactured by Merck Group

The Mouse anti-vinculin hVin-1 is a laboratory reagent used for the detection and analysis of vinculin, a cytoskeletal protein that plays a role in cell-cell and cell-matrix adhesion. This monoclonal antibody recognizes the human vinculin isoform and can be used in various immunological techniques, such as Western blotting, immunoprecipitation, and immunofluorescence microscopy, to study the distribution and expression of vinculin in biological samples.

Cell were fixed in 4% (vol/vol) paraformaldehyde (Alfa-Aeser) for 15 min at RT, permeabilized with 0.1% (vol/vol) Triton X-100 (EMD Millipore) for 3 min, and blocked with 1% (vol/vol) bovine serum albumin (BSA; Thermo Fisher) for 30 min in a humid chamber. Cells were incubated with primary antibodies for 2 h, rinsed with 1% BSA in PBS, and then incubated with secondary antibodies and phalloidin (3:500; Thermo Fisher Scientific) for 30 min in a humid chamber. The following primary antibodies were used for immunostaining: mouse anti-vinculin hVin-1 (1:1000; Sigma) and YAP (D8H1X) XP Rabbit mAb (1:1000; Cell Signaling). As secondary antibodies we used Alexa Fluor 488 goat anti-mouse (1:500) and Alexa Fluor 488 goat anti-rabbit (1:500), both from Life Technologies. Finally, cells were incubated with NucBlue Live ReadyProbes Reagent (Thermo Fisher Scientific) for 20 min in PBS to stain nuclei. Samples were rinsed in PBS and stored in PBS at 4°C in the dark.

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.
