Product details
F-actin Staining Kit - Red Fluorescence | Cytopainter (ab112127) fluorescence imaging kits are a set of fluorescence imaging tools for labeling sub-cellular organelles such as lysosomes, mitochondria, and actin filaments. The selective staining of cell compartments provides a powerful method for studying cellular events in a spatial and temporal context.
ab112127 is designed to stain F-actins in fixed cells with red fluorescence. The red fluorescent phalloidin conjugate, which is selectively bound to F-actins, is a high-affinity probe for F-actins. The red fluorescent phalloidin conjugate has Ex/Em = 594/610 nm. Used at nanomolar concentrations, phallotoxins can be conveniently used to label, identify and quantitate F-actins in formaldehyde-fixed and permeabilized tissue sections, cell cultures or cell-free experiments. The red fluorescent phalloidin conjugate has good thermal and photo stability.
ab112127 provides all the essential components with an optimized labeling protocol. It is an excellent tool for preserving fluorescent images of particular cells, and can also be used for fluorescence microscope demonstrations.
ab112127 should be stored dessicated.

Biological function summary
The actin cytoskeleton plays integral roles in maintaining cell shape providing mechanical resistance against deformation and driving important cellular processes such as endocytosis cell division and motility. F-actin forms part of numerous protein complexes interacting with other proteins like myosin to facilitate muscle contraction and cellular transport. Within cells F-actin is dynamic readily polymerizing and depolymerizing in response to cellular signaling making it essential for cytoskeletal remodeling and cellular adaptability.
Pathways
F-actin is central to various signaling cascades underlying processes like cell signaling and intracellular transport. Notably it participates in the Rho family GTPase pathway affecting cell cytoskeleton organization and motility. It also interacts with proteins like cofilin and profilin which regulate actin polymerization and treadmilling dynamics respectively. These interactions highlight F-actin's involvement in complex cellular pathway regulation processes essential for maintaining cellular homeostasis and adaptability.
