Form Information
Form: Lyophilized
Concentration: 300units/ml
Purification: purified
Storage Buffer: methanol
Preservative: no preservative
Storage Conditions: -20°C
Product Specific Information
Format: 300 units of lyophilized DyLight 488-Phalloidin (300 units/ml) in methanol. Prepare stock solution by adding 1000µl of pure methanol to the vial and gently mix.

21833 has been successfully used in immunofluorescence and immunohistochemistry. DyLight 488-Phalloidin has an excitation/emission of 495/521nm and molecular weight of 1582.65 g/mole.

DyLight 488-Phalloidin Stock Solution is prepared in methanol, and is also soluble in DMF, or DMSO. The unused Stock Solution should be promptly stored at -20°C in a foil pouch with desiccant, and protected from light. The stock solutions are stable for at least one year. Staining cells with some of the DyLight Phalloidin conjugates may require the use of a higher concentration of the phalloidin conjugate; therefore to minimize the amount of methanol added to the cells, the vial contents could be dissolved in 0.5 mL methanol to yield a final concentration of 600units/mL.

Working solution of 1unit/mL (per 96-well plate) can be prepared by diluting 20µl of the Stock Solution in 5.98 ml of PBS and mixing well. Typical staining procedure adds 50µl of Working Solution (i.e. 1 to 5 unit/ml) to a each well. Incubate cells in the dark for 30 minutes at room temperature (optimal staining times varies from 10 minutes to 3 hours depending on cell type). Aspirate and wash cells three times in PBS after incubation. If desired, probe with specific primary antibodies followed by secondary antibodies conjugated to any compatible fluorophores before using DyLight 488-Phalloidin conjugate.
General Information
Phalloidin is a bicyclic peptide that belongs to a family of toxins isolated from the deadly Amanita phalloides “death cap” mushroom and is commonly used as a counterstain (similar to DAPI or Hoechst) in cell biology and histology imaging applications to selectively label F-actin in fixed cells, permeabilized cells, and cell-free experiments. Labeled phalloidin conjugates have similar affinity for both large and small filaments and bind in a stoichiometric ratio of about one phallotoxin per actin subunit in both muscle and non-muscle cells. Phalloidins reportedly do not bind to monomeric G-actin, unlike some antibodies against actin. The dynamics of the actin polymerization in cells are important for a variety of cellular processes from cell motility to cell shape, from muscular contraction to cytokinesis, and more.

    Immunofluorescent analysis of Phalloidin (green) in primary cultured cortical neurons. Primary cortical neurons were isolated and cultured using the Primary Neuron Isolation Kit (Product # 88280). Neurons were grown in a 35mm glass bottom culture dish at a density of 500,000 cells per well. At day 21, neurons were fixed with 4% paraformaldehyde and probed with Dylight 488 Phalloidin (Product # 21833) at a dilution of 1:500 in HBSS (Product # 88284) for 10-15 minutes at room temperature. Cells were washed twice with HBSS, and visualized by fluorescence microscopy. Images were taken at 40X magnification on a Carl Zeiss microscope (AxioVision Rel. 4.7). Note: Representative Phalloidin-labeled dendritic segments studded with mature dendritic spines from primary cultured cortical neurons are shown.
