Cell Navigator® F-Actin Labeling Kit *Blue Fluorescence*

Cell Navigator® F-Actin Labeling Kit

Blue Fluorescence

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

Selective F-actin labeling: Uses iFluor® 350-Phalloidin to bind filamentous actin
Blue fluorescence detection: Provides excitation and emission maxima of approximately 345 nm and 450 nm, respectively
Convenient kit format: Includes fluorescent phalloidin and labeling buffer for 500 tests
Applications: Supports fluorescence imaging of actin filaments and cytoskeletal organization in fixed samples

Fluorescence images of HeLa cells fixed with 4% formaldehyde then stained with Cell Navigator® F-Actin Labeling Kit *Blue Fluorescence* in a Costar black 96-well plate. Cells were labeled with iFluor® 350-Phalloidin (Cat#22660) without (A) or with (B) pre-treatment of phalloidin for 10 minutes.

Overview

Cell Navigator® F-Actin Labeling Kit uses iFluor® 350-Phalloidin to selectively label F-actin with blue 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® 350-Phalloidin and Labeling Buffer, with sufficient reagents for 500 tests. The probe has excitation and emission maxima of approximately 345 nm and 450 nm, respectively, and can be imaged using a DAPI-compatible filter set. Cell Navigator® F-Actin Labeling Kit supports fluorescence microscopy studies of actin filament distribution and cytoskeletal organization.
