The Actin Polymerization Biochem Kit™ is based on the enhanced fluorescence of pyrene conjugated actin that occurs during polymerization. The enhanced fluorescence that occurs when pyrene G-actin (monomer) forms pyrene F-actin can be measured in a fluorimeter to follow polymerization over time. Also, by using preformed pyrene F-actin, it is possible to follow depolymerization. Both cell/tissue extracts and purified proteins ca…

The G-LISA™ assay uses a 96-well plate coated with RBD domain of Rho-family effector proteins. The active GTP-bound form of the Rho-family protein, but not the inactive GDP-bound form, from a biological sample will bind to the plate. Bound active Rho-family protein is then detected by incubation with a specific primary antibody followed by a secondary antibody conjugated to HRP. The signal is then developed with OPD or chemilu…

The most reproducible and accurate method of determining the amount of filamentous actin (F-actin) content versus free globular-actin (G-actin) content in a cell population is to use Western blot quantitation of F-actin and G-actin cellular fractions. The general approach is to homogenize cells in F-actin stabilization buffer, followed by centrifugation to separate the F-actin from G-actin pool. The fractions are then separate…
