Beta actin antibody

Manufactured by Proteintech
Sourced in United States

The beta-actin antibody is a research tool used to detect the presence and quantify the levels of the beta-actin protein, which is a ubiquitous and highly conserved cytoskeletal protein found in all eukaryotic cells. The antibody can be used in various laboratory techniques, such as Western blotting, immunofluorescence, and immunohistochemistry, to study the expression and localization of beta-actin in different cell types and tissues.

Total proteins from tobacco K326 inoculated leaves at 1 dpi and systematic leaves at 3, 5, 7, 9 dpi, as well as the upper two leaves of N. benthamiana plants were extracted using a Plant Protein Extraction Kit (Solarbio, Shanghai, China) and quantified using the BCA protein quantification kit (Beyotime, Shanghai, China), respectively. After the completion of electrophoresis, the proteins separated by 12% SDS-PAGE were transferred to 0.20 μm polyvinylidene fluoride (PVDF) membranes (Millipore, Billerica, USA), which were then incubated in blocking solution for one hour (Solarbio, Shanghai, China). PVY CP monoclonal antibody was used at dilution of 1: 1000 (Youlong, Shanghai, China). Beta-actin antibody was used at dilution of 1: 5000 (Proteintech, Chicago, USA).

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.
