Mucin Probe, StcE is a proteolytically inactive mutant (E447D) form of Mucinase StcE that maintains ability to tightly bind mucin proteins. The recombinant protein carries a 3XFLAG tag and is also enzymatically biotinylated at the C-term of the protein. While there are many applications, this product is designed to probe mucin dense tissues. It will non-covalently, and selectively bind to Mucin-domain glycoproteins with dense O-linked glycosylation. Secondary reporting tools can then be used to bind the probe using its FLAG^® tag or Biotin conjugate.
