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.

Cayman Chemical 12mthyl MyrIstIc ACD mthy 25mg
A methylated fatty acid methyl ester; has been found in vermicomposts of cattle manure, carica papaya leaves, and cuticular wax of K. africana; a volatile compound in lipid-lowering granulated tea; levels are decreased in nifurtimox-treated T. cruzi compared to non-treated controls
Fluorochrome Inc Fluoro-Gold, 50 mg
Hydroxystilbamidine (also called Fluoro-Gold) has been used extensively as a retrograde tracer for neurons and also a histochemical stain. Fluoro-Gold can undergo retrograde axonal transport, it shows extensive filling of dendrites, and has a high resistance to fading.
Sigma Aldrich Fine Chemicals Biosciences Sera MagTM magnetic carbox
Sera-Mag(TM) SpeedBeads(TM) and Sera-Mag(TM) Carboxylate-Modified Magnetic Particles combine a fast magnetic response time and high binding capacity with a large surface area high sensitivity stability physical integrity and fast reaction kinetics. Covalent coupling of biomolecules such as proteins and nucleic acids to carboxyl groups on the surface is easily accomplished using our standard coupling technology. The core of the particle is made by a free radical emulsion polymerization of styrene and acid monomer. One (Sera-Mag(TM)) or two (Sera-Mag(TM) SpeedBeads(TM)) layers of magnetite are then coated onto this core while the surface is modified to minimize non-specific binding of proteins.
