Active Biotinylated Recombinant Proteins

Biotinylated proteins can be powerful tools to assess protein/protein interactions in a range of assay formats, including immunoprecipitation, flow cytometry, immunoassays, and surface plasmon resonance. To be successful, it is crucial that biotinylation does not affect protein activity. For this reason, we hold our biotinylated proteins to the same specifications as their unlabeled counterparts.

Features and benefits

  • New Avi-Tag proteins allow for more control over the extent and consistency of biotinylation.
  • Labeling via carbohydrates is less likely to affect binding activity
  • Traditional labeling via amines can produce enhanced sensitivity
  • All proteins are tested in the same bioassay as unlabeled proteins to ensure specificity
