Recombinant human DNase I protein (Active) (ab73430)


  • Product name

    Recombinant human DNase I protein (Active)
  • Biological activity


    One Dnase unit results in an increase in absorbance at 260nm of 0.001/minute at 25°C when acting upon highly polymerized solution of DNA at pH-5. (Also, 0.005 Kunitz unit digests 1µg of lambda phage DNA in 10 minutes at 37°C in 50mM Tris, 1mM Mg2+, pH 7.8 in a 50ul reaction volume.)

  • Function

    Among other functions, seems to be involved in cell death by apoptosis. Binds specifically to G-actin and blocks actin polymerization.
  • Tissue specificity

    Principally in tissues of the digestive system. Highest levels found in urine, but also relatively abundant in semen and saliva.
  • Sequence similarities

    Belongs to the DNase I family.
  • Cellular localization

    Secreted. Nucleus envelope. Secretory protein, stored in zymogen granules and found in the nuclear envelope.
