Features

ActinBrite™ High Affinity Phalloidin Conjugates are novel phalloidin conjugates of fluorescent dyes that were designed to preserve high phalloidin affinity for F-actin, resulting in bright staining that can be imaged more than one month after staining with minimal loss of signal or specificity.

  • Novel fluorescent phalloidin conjugates designed to preserve F-actin binding
  • Allows stained samples to be stored for over a month or longer depending on the conjugate
  • Available in 5 colours from green to near-IR for seamless multiplexing
  • Serve as direct replacements for any phalloidin conjugate

Reliable F-actin Staining, No Fading
Fluorescent phalloidins are popular tools for staining F-actin in fixed cells and tissues, but traditional dye conjugation can reduce their binding affinity—leading to weaker, less stable staining compared to other probes like labelled antibodies. As a result, phalloidin-stained samples typically lose signal within a week, especially when used with standard fluorescence mounting media.

ActinBrite™ High Affinity Phalloidin Conjugates solve this problem by preserving strong F-actin binding, delivering bright, reliable staining that lasts. With ActinBrite™, samples can be imaged after for a month or more (depending on the conjugate and mounting method)—making delayed imaging easier and more dependable.

Biotium offers a wide selection of traditional and novel stains for labelling cell structures, organelles, or monitoring viability.
