Recombinant Streptavidin

• Background:

  Streptavidin is a tetrameric protein composed of identic subunits. Each subunit binds one biotin molecule with a KD of ~1×10-15 M. The preparation contains an N- and C-terminal shortened variant (core streptavidin) with improved properties concerning homogeneity, solubility, resistance towards proteolytic degradation and accessibility of the biotin binding pocket as compared to native streptavidin.

• Molecular Weight:

  Approximately 52, per tetramer.

• CAS Number:

  9000-83-3
