Biotin ligase

  • BirA-500: BirA biotin-protein ligase standard reaction kit

    The BirA biotin-protein ligase adds d-biotin covalently to biotin-acceptor peptides/proteins via an ATP intermediate (biotinyl 5’-adenylate) in a highly efficient and targeted manner. This kit includes 40ug of BirA enzyme and all necessary buffers for those who require smaller scale reactions or less frequent use of the BirA biotinylation reaction in their work.

  • Bulk BirA: BirA biotin-protein ligase bulk reaction kit

    The BirA biotin-protein ligase adds d-biotin covalently to biotin-acceptor peptides/proteins via an ATP intermediate (biotinyl 5’-adenylate) in a highly efficient and targeted manner. This kit includes 300 µg of BirA enzyme for those who require larger scale reactions or more frequent use of the BirA biotinylation reaction in their work.

BIS-300

BIS-200

  • BIO-200 biotin solution

    1.5mL of 500 μM d-biotin solution for BirA biotin-protein ligase reaction conditions that may require extra biotin. This is the same d-biotin solution as provided in the BirA-500 and Bulk BirA in-vitro biotinylation reaction kits.

BIS-500

  • BIO-500 biotin solution

    10 ml Biotin solution at higher concentration (5 mM) in 10 mM Bicine (pH 8.3). Suitable for supplimenting induction growth media and large scale biotin ligase reactions. Solution is filter sterilized. Store at 4oC.
