Magnetic Particles for Bioseparation (Magnosphere™ S300/Streptavidin)

Background

Magnosphere MS300/Streptavidin particles are Streptavidin coated magnetic microparticles for bioseparation. The surfaces of Magnosphere MS300/Streptavidin particles are covered with hydrophilic polymer to achieve both low non-specific binding and no inhibition of enzyme activity. Consequently, Magnosphere MS300/Streptavidin particles can be used for PCR amplification systems or enzyme immunoassay systems.

Application

PCR, quantitative PCR
DNA hybridization,
Capturing biotinylated proteins
Enzyme immunoassay

Example of use 1 Influence on PCR

Added amount of Magnosphere to the PCR cocktail (mg/tube)

Various amount of Magnosphere MS300/Streptavidin were added to PCR cocktail with defined amount of 100bp DNA and the DNA were amplified by qPCR. Obtained Threshold Cycle (Ct) were plotted against added bead amount. As a result, Ct values were not affected by addition of Magnosphere MS300/Streptavidin through 3mg/tube.

Example of use 2

Added amount of biotin labeled DNA (copies)

Added vs. immobilized DNA on the Magnosphere MS300/Streptavidin. According to the protocol above, various amount of biotin labeled 100bp DNA were reacted with the Magnosphere MS300/Streptavidin. The amount of immobilized DNA were quantitated through a qPCR using bead fraction.

Feature and Advantages

  • High affinity to biotinylated proteins or nucleotides
  • Uniform particle size
  • Superparamagnetic
  • Rapid magnetic responsiveness
  • Low non-specific binding
  • Free of enzyme activity
