特性

Our Abpromise guarantee covers the use of ab51277 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

  • 生理活性Specific activity: 6,000-12,000units/mg. Enzymatic activity was confirmed by measuring the amount of enzyme hydrolyzing 1 nmole of p-nitrophenyl phosphate (pNPP) per minute at 37°C, pH7.5 using 10mM of substrate.
    Activity Assay:
    1. Prepare a 200ul reaction mix into a suitable container: The final concentrations are 10mM Tris(pH7.5), 50mM NaCl, 2mM DTT, 1mM MnCl2, 10mM pNPP.
    2. Pre-warm reaction mix in heat block at 37°C
    3. Add recombinant PTP1B solution with various concentrations (2ug, 3ug, 4ug) in 200ul reaction buffer.
    4. Mix by inversion and Incubate at 37°C for 10minutes.
    5. Stop the reaction by adding the 800ul of 0.1N NaOH.
    6. Record the absorbance at 405nm

  • 配列類似性Belongs to the protein-tyrosine phosphatase family. Non-receptor class 1 subfamily.
    Contains 1 tyrosine-protein phosphatase domain.
  • 翻訳後修飾Oxidized on Cys-215; the Cys-SOH formed in response to redox signaling reacts with the alpha-amido of the following residue to form a 4-amino-3-isothiazolidinone serine cross-link, triggering a conformational change that inhibits substrate binding and activity. The active site can be restored by reduction.
