      Product Information
      FormatAffinity Purified
      • CONTROL ANTIGEN: Included free of charge with the antibody is 120 μg of control antigen (lyophilized powder). The stock solution of the antigen can be made up using 100 μL of PBS. For positive control, in Western blot using 20 ng of protein per minigel lane. For negative control, preincubate 3 μg of fusion protein with 1 μg of antibody for one hour at room temperature. Optimal concentrations must be determined by the end user.
      PresentationAffinity purified immunoglobulin. Lyophilized from phosphate buffered saline, pH 7.4, containing 1% BSA and 0.025% sodium azide as a preservative. Reconstitute with 200 μL of sterile deionized water. Centrifuge antibody preparation before use (10,000 xg for 5 min).
      ApplicationDetect Potassium Channel IsK using this Anti-Potassium Channel IsK Antibody validated for use in WB.
      Key Applications
      • Western Blotting
      Application NotesWestern blot: 1:100-1:200 on rat heart membranes, 1:200-1:1,000 on IsK expression Sf9 cells using ECL.

      Dilutions should be made using a carrier protein such as BSA (1-3%)

      Optimal working dilutions must be determined by the end user.
      Biological Information

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P15382 # Ancillary protein that assembles as a beta subunit with a voltage-gated potassium channel complex of pore-forming alpha subunits. Modulates the gating kinetics and enhances stability of the channel complex. Assembled with KCNQ1/KVLQT1 is proposed to form the slowly activating delayed rectifier cardiac potassium (IKs) channel. The outward current reaches its steady state only after 50 seconds. Assembled with KCNH2/HERG may modulate the rapidly activating component of the delayed rectifying potassium current in heart (IKr).
      SIZE: 129 amino acids; 14675 Da
      SUBUNIT: Associates with KCNQ1/KVLQT1 and KCNH2/HERG.
      SUBCELLULAR LOCATION: Membrane; Single-pass type I membrane protein.
      TISSUE SPECIFICITY: Expressed in heart, lung, kidney, testis, ovaries, small intestine, peripheral blood leukocytes. Not detected in pancreas, spleen, prostate and colon. Restrictively localized in the apical membrane portion of epithelial cells.
      PTM: Phosphorylation inhibits the potassium current (By similarity).
      DISEASE: "SwissProt: P15382 # Defects in KCNE1 are a cause of the autosomal recessive Jervell and Lange-Nielsen syndrome (JLNS) [MIM:220400]. JLNS comprises profound congenital sensorineural deafness associated with syncopal episodes. These are caused by ventricular tachyarrhythmia secondary to abnormal repolarization, manifested by a prolonged QT interval on the electrocardiogram. & Defects in KCNE1 are the cause of long QT syndrome type 5 (LQT5) [MIM:176261]. Long QT syndromes are heart disorders characterized by a prolonged QT interval on the ECG and polymorphic ventricular arrhythmias. They cause syncope and sudden death in response to exercise or emotional stress. KCNE1 mutants form channels that open slowly and close rapidly, thereby diminishing potassium currents."
      SIMILARITY: SwissProt: P15382 ## Belongs to the potassium channel KCNE family.
