RNasin (RNase inhibitor)

Electrophoresis grade


RNasin is a ribonuclease inhibitor extracted from human placenta with a molecular weight 51 kDa. It inhibits the activity of RNase by specifically binding up to RNase with a non-covalent bond. RNasin, free of RNase or Nickase, can maintain its activity at pH from 5 to 8, and the highest one at pH7.8. The concentration of RNasin is 20~40 units/µl. Store at -20℃.
