Toolkit description
|
The Actin-Toolkit Fluorescence Microscopy was developed to analyze and demonstrate the effect of ligands on actin polymerization, or ligand-induced formation of actin bundles and networks. In the assays Rhodamine-Actin is mixed with the ligand to observe the effects on either G- or F-actin. In contrast to staining with phalloidin conjugates, which can interfere with ligand binding sites on the actin molecule, no such observations were made with rhodamine labeled actin.
The Toolkit further contains unlabeled actin (0.5mg α-skeletal muscle actin). A mixture of both excludes possible interference of the fluorescent actin conjugates on ligand binding sites.
Several standardized experiments are described step-by-step in the handbook supplied with the kit. In combination with the actin buffers contained in the kit, error-free handling is guaranteed. The kit contains 4x100µg of α-skeletal muscle Rhodamine-Actin conjugates and buffers to keep the actin functional.
