ICC/IF Use a concentration of 5 µg/ml.

ターゲット情報

  • 機能
    Pore-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.
  • 組織特異性
    Highly expressed throughout the brain. Expression is very low or absent in other tissues.
  • 配列類似性
    Belongs to the potassium channel family. D (Shal) (TC 1.A.1.2) subfamily. Kv4.2/KCND2 sub-subfamily.
  • ドメイン
    The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.
  • 翻訳後修飾
    Phosphorylated on serine and threonine residues.
  • 細胞内局在
    Cell membrane. Cell projection > dendrite. Detected in dendrites in cultured hippocampal neurons. Association with KCNIP2 probably enhances cell surface expression.

    Secondary
    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 70 kDa
    Observed band size : 74 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 90 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 4 minutes
  • ab123543 stained SKNSH cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab123543 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
