Conjugating fluorescent dye to actin

WebPhalloidin is a peptide that can be conjugated to fluorescent dyes, such as fluorescein, and used to label actin in cells. Phalloidin-fluorescein was added to dividing, ciliated cells in culture. Where will the fluorescence be localized in the cells when looking at the treated cultures using fluorescence microscopy? Web84 rows · Fluorescent phalloidins only bind to the native quaternary structure of F-actin which provides a low background. The correct fixation condition for phalloidin binding is 3.7% (v/v) paraformaldehyde in PBS …
