Alexa 488 and alexa 568 conjugated phalloidin

Manufactured by Thermo Fisher Scientific

Alexa 488- and Alexa 568-conjugated phalloidin are fluorescent stains used to label and visualize actin filaments in cells. Phalloidin is a toxin that binds specifically to F-actin, and the Alexa Fluor dyes provide bright fluorescent labeling of the actin cytoskeleton. These products are commonly used in fluorescence microscopy applications to study cell structure and dynamics.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
