BioLock Biotin Blocking Solution
BioLock is a ready-to-use biotin blocking solution containing avidin, which strongly binds to biotin and biotinylated proteins, but not to Strep-tag®II or Twin-Strep-tag® fusion proteins. This prevents unspecific binding of biotin/biotinylated proteins to Strep-Tactin® or Strep-Tactin®XT resins, ensuring optimal binding capacity and high purity of the target protein.
