Using these systems, biotinylated lysine residues are incorporated into nascent proteins during translation, eliminating the need for labeling with [35S]methionine or other radioactive amino acids. This biotinylated lysine is added to the translation reaction as a precharged ε-labeled biotinylated lysine-tRNA complex (Transcend tRNA) rather than a free amino acid. After SDS-PAGE and electroblotting, the biotinylated proteins can be visualized by binding either Streptavidin-Alkaline Phosphatase (Streptavidin-AP) or Streptavidin-Horseradish Peroxidase (Streptavidin-HRP), followed either by colorimetric or chemiluminescent detection.

  • Sensitive: The biotin tag allows detection of 0.5 to 5ng of translated protein
  • Safe: No radioisotope handling, storage or disposal is required
  • Fast: Labeled proteins can be detected three to four hours after gel electrophoresis
  • Flexible: Results can be visualized by using colorimetric or chemiluminescent detection
  • IRNA available separately (PR-L5061)
