Application Abreviews Notes
IHC-P 1/50. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
WB 1/1000 - 1/10000. Detects a band of approximately 37 kDa (predicted molecular weight: 31 kDa).
Flow Cyt 1/30.

IP 1/40.


  • Function

    Hydrolyzes N(G),N(G)-dimethyl-L-arginine (ADMA) and N(G)-monomethyl-L-arginine (MMA) which act as inhibitors of NOS. Has therefore a role in the regulation of nitric oxide generation.
  • Tissue specificity

    Detected in brain, liver, kidney and pancreas, and at low levels in skeletal muscle.
  • Sequence similarities

    Belongs to the DDAH family.
