General description

Streptavidin-coated polystyrene-based magnetic microparticles are a size standard, fit for particle size distribution (PSD) analysis of test samples.
The accurate diameter of 1 μm is determined by methods described by the National Institute of Standards and Technology (NIST, USA), such as:
  • Transmission electron microscopy
  • Scanning electron microscopy
  • Optical microscopy
  • COULTER COUNTER particle size analyzer with HDF system.
  • The measuring instruments are calibrated using standards obtained from the Community Bureau of Reference (BCR, Belgium: Standards RM 165, 166 or 167) and from the NIST (SRM 1690, 1691 or 1692). This analytical standard product is made up of superparamagnetic polystyrene particles.

Superparamagnetic polystyrene particles

Application

Used to calibrate and test particle size analyzers. Easily conjugated with biotin, making it useful for several detection assays.
