Our Abpromise guarantee covers the use of ab1383 in the following tested applications.

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

Application Abreviews Notes
WB Use a concentration of 1 - 3 µg/ml. Detects a band of approximately 30 kDa (predicted molecular weight: 30 kDa).Can be blocked with Human DDAH2 peptide (ab22866). Please note that DDAH2, according to NP_039268, has a consensus glycosylation site. Glycosylation can affect migration of proteins on SDS-PAGE [Hames, B.D and Rickwood, D., eds. Gel electrophoresis of proteins: a practical approach. Oxford University Press].
IHC-FoFr Use at an assay dependent dilution. PubMed: 21408057
ICC/IF Use at an assay dependent dilution.


  • FunctionHydrolyzes 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 specificityDetected in heart, placenta, lung, liver, skeletal muscle, kidney and pancreas, and at very low levels in brain.
  • Sequence similaritiesBelongs to the DDAH family.
