GenScript streptavidin MagBeads are coated with highly purified streptavidin for purification of biotinylated proteins and nucleic acids.

  • Quick and convenient separation accomplished by magnetic force
  • High binding capacity with more than 60 nmol D-Biotin/ml settled beads
  • Extremely low nonspecific binding
  • Store at 4 °C

The beads are supplied as 25% slurry in phosphate buffered saline (PBS), pH 7,4, containing 20% ethanol. Streptavidin is a biotin-binding protein found in the culture broth of the bacterium S. avidinii.

Streptavidin binds 4 moles of biotin per mole of protein with an extremely high affinity. Streptavidin lacks carbohydrate side chains present on avidin and has an isoelectric point of 6,5 (vs 10 for avidin) close to where most useful biological interactions occur. As a result, streptavidin frequently exhibits much lower non-specific binding than avidin does.
