Our Abpromise guarantee covers the use of ab49433 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 1.25 µg/ml. Detects a band of approximately 38 kDa (predicted molecular weight: 43 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
ELISA Use at an assay dependent concentration.

ELISA: titre using peptide based assay: 1/1562500.


  • FunctionpH-dependent, voltage-insensitive, background potassium channel protein. Rectification direction results from potassium ion concentration on either side of the membrane. Acts as an outward rectifier when external potassium concentration is low. When external potassium concentration is high, current is inward.
  • Tissue specificityWidespread expression in adult. Strongest expression in pancreas and placenta. Lower expression in brain, lung, prostate, heart, kidney, uterus, small intestine and colon.
  • Involvement in diseasePulmonary hypertension, primary, 4
  • Sequence similaritiesBelongs to the two pore domain potassium channel (TC 1.A.1.8) family.
  • Cellular localizationMembrane.
