STEMCELL Technologies Phalloidin, iFluor™ 488, Size: 300 Tests
Phalloidin is a heptapeptide derived from the poisonous mushroom Amanita phalloides. Phalloidin binds with a high specificity to F-actin filaments in cells, preventing filament depolymerization. Fluorescently labeled phalloidin can be used in labeling, identification, and quantitation of F-actin in formaldehyde-fixed and permeabilized cells. Fluorescently labeled phalloidin has lower non-specific binding compared to actin antibodies across most species of plants and animals, which provides low background and high contrast during imaging.

AAT Bioquests iFluor dyes are optimized for labeling proteins in particular antibodies. This catalog is for 5 mg.
STEMCELL Technologies GloCell™ Fixable Viability Dye Violet 540, Size: 100 Tests
GloCell™ Fixable Viability Dye Violet 540 is a fluorescent cell viability dye for staining live/dead mammalian cells in applications such as flow cytometry. The dye irreversibly binds intracellular and cell surface amine groups and can be utilized prior to fixation, permeabilization, or cryopreservation. Cells with compromised plasma membranes become permeable to the GloCell™ dye, resulting in a greater fluorescence compared to live cells in a cell viability assay.GloCell™ Fixable Viability Dye Violet 540 is excited by the violet laser at 405 nm and it has a fluorescence emission maximum of 540 nm that can be detected using the 525/50 band pass filter used to detect AmCyan.
Cytoskeleton, Inc. Flipper-TR Membrane Sensor, Real-Time Measurement, Non-Invasive Fluorescence, 50 nmol
The Flipper-TR Membrane Sensor is an advanced fluorogenic probe designed for real-time measurement of plasma membrane tension in live cells. It utilizes Fluorescence Lifetime Imaging Microscopy (FLIM) to provide insight into membrane mechanics, distinguishing it from other probes. Its unique sensing mechanism allows fluorescence only when incorporated into lipid membranes, making it ideal for diverse organisms, including bacteria and plants. This probe enhances mechanobiology studies by simplifying complex methodologies.

Cayman Chemical BIotIn hydrazIde 500mg
A biotinyl derivative used to label surface functional groups, antibodies, lectins, sugars, nucleic acids, or molecules with free carboxylic or keto groups; probe for determining protein carbonylation
Sigma Aldrich Fine Chemicals Biosciences Phalloidin Atto 390 suitab
Atto 390 Phalloidin is a novel fluorescent label with a coumarin structure. The dye is intended for application in the area of life science e.g. labeling of DNA RNA or proteins. Characteristic features of the label are high fluorescence quantum yield large Stokes-shift good photostability and low molecular weight.Phalloidin is a fungal toxin isolated from the poisonous mushroom Amanita phalloides. Its toxicity is attributed to the ability to bind f actin in liver and muscle cells. As a result of binding phalloidin actin filaments become strongly stabilized. Phalloidin has been found to bind only to polymeric and oligomeric forms of actin and not to monomeric actin. The dissociation constant of the actin-phalloidin complex has been determined to be on the order of 3 x 10-8. Phalloidin differs from amanitin in rapidity of action at high dose levels death of mice or rats occurs within 1 or 2 hours.
