Toolkit description

The interaction of G-actin with lignds is highly specific. Thus, a positive proof of this interaction strongly indicates that G-actin binding is a biological function of the ligand. All assays of the Actin-Toolkit G-Actin Binding are performed with G-actin coupled to Sepharose™ (ActinBeads), with the option to use gelsolin as reference protein. 

The handbook included in the kit guides through different experimental approaches. In combination with the buffers provided the ActinBeads are kept functional and are prevented from denaturing during assay performance. The Actin Toolkit G-Actin Binding contains 4x250µl G-actin (50% slurry) conjugated to Sepharose™ to be spun at low centrifugal forces. Under these conditions ligands bound to G-actin will be co-precipitated with actin. SDS-PAGE will reveal binding of G-actin binding ligands.  

The Actin-Toolkit G-Actin Binding is further used for assays ranging from the determination of binding stoichiometries up to the variation of buffer conditions to possibly optimize G-actin binding. The kit is available with Sepharose™ conjugated actin from rabbit skeletal (Cat. # 8020-01) . Further components are gelsolin, and buffers to keep actin functional. A handbook introduces to G-actin and guides through the experimental use of ActinBeads. We guarantee stable performance of all kit components when stored at -70°C upon arrival for at least 6 months.
