Alexa Fluor™ 488 Phalloidin - Thermo Fisher Scientific

WebAlexa Fluor ® 488 Phalloidin allows researchers to fluorescently stain the cytoskeleton through the binding of phalloidin to F-actin. This product is intended for use on fixed and permeabilized samples due to the toxicity associated with phalloidin. After reconstitution the stock solution provides enough material to perform 300 assays based on ... Biosynthesis Phalloidin is a bicyclic heptapeptide containing an unusual cysteine-tryptophan linkage. The gene coding for synthesis of phalloidin is part of the MSDIN family in the Death Cap mushroom and codes for a 34 amino acid propeptide. A proline residue flanks the seven-residue region that will later … See more Phalloidin belongs to a class of toxins called phallotoxins, which are found in the death cap mushroom (Amanita phalloides). It is a rigid bicyclic heptapeptide that is lethal after a few days when injected into the bloodstream. … See more Phalloidin binds F-actin, preventing its depolymerization and poisoning the cell. Phalloidin binds specifically at the interface between F-actin subunits, locking adjacent subunits together. Phalloidin, a bicyclic heptapeptide, binds to actin filaments much … See more Phalloidin is much smaller than an antibody that would typically be used to label cellular proteins for fluorescent microscopy which … See more • Fungi portal • Cytoskeleton See more Phalloidin was one of the first cyclic peptides to be discovered. It was isolated from the death cap mushroom and crystallized by See more Soon after its discovery, scientists injected phalloidin into mice and discovered its LD50 is 2 mg/kg via IP injection. When exposed to the … See more The properties of phalloidin make it a useful tool for investigating the distribution of F-actin in cells by labeling phalloidin with fluorescent analogs and using them to stain … See more WebPhalloidin 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 … download grade 12 past papers 2021
