How Does HiBiT Compare With Other Epitope Tags?

HiBiT is an 11-amino acid epitope tag enabling high-throughput, live-cell protein quantification via ultra-sensitive bioluminescence detection. The high-affinity Anti-HiBiT Monoclonal Antibody also enables applications like immunoprecipitation-mass spectrometry at endogenous levels.

HiBiT Is Different from Traditional Epitope Tags

  • In traditional Western blotting, you need an antibody to your protein of interest or epitope tag, and a method for detecting that antibody.
  • With HiBiT, no antibody is needed, eliminating processing steps and minimizing hands-on time.

Benefits of HiBiT Protein Tagging

  • Easy quantitation and detection
  • No blocking needed
  • No background, unlike antibody-based methods, with HiBiT blotting it doesn't matter if the detection reagent binds non-specifically to the membrane. There will be no luminescent signal except where it has bound to a HiBiT tagged protein.

How HiBiT Tagging Is Being Applied

  • Monitoring protein abundance in the cell
  • Protein degradation research
  • Monitoring receptor internalization
  • Inserting and detecting CRISPR knock-ins
