Alexa Fluor 633 Phalloidin from Life Technologies


Alexa Fluor® 633 phalloidin is a high-affinity F-actin probe
conjugated to our bright, photostable, far-red fluorescent Alexa
Fluor® 633 dye.

  • Selectively stains F-actin

  • Outstanding fluorescence performance

  • Excitation⁄Emission: 632⁄647 nm

  • Superior to antibody staining

  • Optimal for fixed and permeabilized samples

Get Superior Results in Actin Staining Studies

Phalloidin is a bicyclic peptide belonging to a family of toxins
isolated from the deadly Amanita phalloides "death cap"
mushroom and is
commonly used in imaging applications to selectively label F-actin.
Fluorescently-labeled phalloidin has virtually identical binding
properties with actin from different species including plants and
animals. Phalloidin binds F-actin with high selectivity while Alexa
Fluor® 633 provides far-red fluorescence of unparalleled brightness
and photostability. Demonstrating very little nonspecific staining,
Alexa Fluor® 633 phalloidin allows high-contrast discrimination of
actin staining.

Use in Multiple Applications

Alexa Fluor® 633 phalloidin can be used to visualize and quantitate
F-actin in tissue sections, cell cultures, or cell-free preparations.
Alexa Fluor® 633 phalloidin staining is fully compatible with other
fluorescent stains used in cellular analyses including fluorescent
proteins, Qdot® nanocrystals, and other Alexa Fluor® conjugates
including secondary antibodies.

For research use only. Not intended for human or animal therapeutic or
diagnostic use.
