Cell Navigator® F-Actin Labeling Kit

Green Fluorescence

Cell Navigator® F-Actin Labeling Kit is designed for selective green fluorescent labeling of filamentous actin (F-actin) in fixed, permeabilized cells.

Selective F-Actin Labeling: Uses iFluor® 488-Phalloidin to bind filamentous actin
Green Fluorescence Detection: Provides excitation and emission maxima of approximately 491 nm and 516 nm, respectively
Convenient Kit Format: Includes fluorescent phalloidin and labeling buffer for 500 tests
Convenient Kit Format: Includes fluorescent phalloidin and labeling buffer for 500 tests

Overview

Cell Navigator® F-Actin Labeling Kit uses iFluor® 488-Phalloidin to selectively label F-actin with green fluorescence. The fluorescent phalloidin conjugate binds actin filaments, enabling visualization of the actin cytoskeleton in formaldehyde-fixed, permeabilized cells and tissue sections.

The kit includes iFluor® 488-Phalloidin and labeling buffer, with sufficient reagents for 500 tests. The probe has excitation and emission maxima of approximately 491 nm and 516 nm, respectively, and can be imaged using a FITC-compatible filter set. Cell Navigator® F-Actin Labeling Kit supports fluorescence microscopy studies of actin filament distribution and cytoskeletal organization.
