Cytiva Sera-Mag SpeedBead Carboxylate-Modified E7 Magnetic Bead Particle, 15 mL Net Content, Sera-Mag

Cytiva Sera-Mag SpeedBead Carboxylate-Modified E7 Magnetic Bead Particle, 15 mL Net Content, Sera-Mag SpeedBead Format, 1 um Particle Size, 60% Magnetite Content, 50 mg/mL Concentration, 4 deg C Storage Temp. Sera-Mag carboxylate-modified magnetic beads and SpeedBeads have free carboxyl groups on the surface for convenient covalent coupling of target molecules (proteins, peptides and amine-modified ligands) via primary amines (NH2). E3 and E7 refer to the different manufacturing process for the beads. E3 and E7 beads behave similarly and we continue to provide both bead types to our customers for test and validation in their chosen application. The core of each particle is made by a free radical emulsion polymerization of styrene and acid monomer. One layer of magnetite with Sera-Mag beads or two layers of magnetite with Sera-Mag SpeedBeads are then coated onto this core, while the surface is modified to minimize non-specific binding of proteins. Due to the extra magnetite layer, SpeedBeads respond twice as fast to a magnetic field as the original Sera-Mag particles - GHC-F (Additional S&H or Hazmat Fees May Apply)
