Our Abpromise guarantee covers the use of ab49348 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
ELISA Use at an assay dependent concentration.

ELISA titre using peptide based assay: 1:12500.

WB Use a concentration of 1.25 µg/ml. Detects a band of approximately 61, 42 kDa (predicted molecular weight: 70 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.


  • FunctionPore-forming (alpha) subunit of voltage-gated rapidly inactivating A-type potassium channels. May contribute to I(To) current in heart and I(Sa) current in neurons. Channel properties are modulated by interactions with other alpha subunits and with regulatory subunits.
  • Tissue specificityHighly expressed in heart and brain, in particular in cortex, cerebellum, amygdala and caudate nucleus. Detected at lower levels in liver, skeletal muscle, kidney and pancreas. Isoform 1 predominates in most tissues. Isoform 1 and isoform 2 are detected at similar levels in brain, skeletal muscle and pancreas.
  • Sequence similaritiesBelongs to the potassium channel family. D (Shal) (TC 1.A.1.2) subfamily. Kv4.3/KCND3 sub-subfamily.
  • DomainThe segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.
  • Cellular localizationMembrane. Cell membrane > sarcolemma.
