Our Abpromise guarantee covers the use of ab32433 in the following tested applications.

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

应用 Ab评论 说明
ICC/IF Use a concentration of 1 µg/ml.
IHC-P Use at an assay dependent concentration. PubMed: 21632505
WB Use a concentration of 1 µg/ml. Detects a band of approximately 70 kDa (predicted molecular weight: 56 kDa).

ab32433 detects a band at 70kDa. While this differs to its predicted molecular weight of 56kDa, this migration has been observed in the literature (PMID: PMC2290329).

IHC-FoFr 1/3000.


  • 功能Mediates the voltage-dependent potassium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a potassium-selective channel through which potassium ions may pass in accordance with their electrochemical gradient.
  • 疾病相关Defects in KCNA1 are the cause of episodic ataxia type 1 (EA1) [MIM:160120]; also known as paroxysmal or episodic ataxia with myokymia (EAM) or paroxysmal ataxia with neuromyotonia. EA1 is an autosomal dominant disorder characterized by brief episodes of ataxia and dysarthria. Neurological examination during and between the attacks demonstrates spontaneous, repetitive discharges in the distal musculature (myokymia) that arise from peripheral nerve. Nystagmus is absent.
    Defects in KCNA1 are the cause of myokymia isolated type 1 (MK1) [MIM:160120]. Myokymia is a condition characterized by spontaneous involuntary contraction of muscle fiber groups that can be observed as vermiform movement of the overlying skin. Electromyography typically shows continuous motor unit activity with spontaneous oligo- and multiplet-discharges of high intraburst frequency (myokymic discharges). Isolated spontaneous muscle twitches occur in many persons and have no grave significance.
  • 序列相似性Belongs to the potassium channel family. A (Shaker) (TC 1.A.1.2) subfamily. Kv1.1/KCNA1 sub-subfamily.
  • 结构域The N-terminus may be important in determining the rate of inactivation of the channel while the tail may play a role in modulation of channel activity and/or targeting of the channel to specific subcellular compartments.
    The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.
  • 翻译后修饰Palmitoylated on Cys-243; which may be required for membrane targeting.
  • 细胞定位Membrane.

  • All lanes : Anti-Kv1.1 potassium channel antibody (ab32433) at 1 µg/ml

    Lane 1 : Brain (Mouse) Tissue Lysate
    Lane 2 : Heart (Rat) Tissue Lysate

    Lysates/proteins at 10 µg per lane.

    Goat Anti-Rabbit IgG H&L (HRP) (ab97051) at 1/10000 dilution
    developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 56 kDa
    Observed band size : 70 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 150 kDa,23 kDa,45 kDa,55 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 8 minutes

    ab32433 detects a band at 70kDa. While this differs to its predicted molecular weight of 56kDa, this migration has been observed in the literature (PMID: PMC2290329).

  • ICC/IF image of ab32433 stained human HEK 293 cells. The cells were PFA fixed (10 min), permabilised in TBS-T (20 min) and incubated with the antibody (ab32433, 1µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to quench autofluorescence and block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).

  • IHC FoFR image of ab32433 stained sections of rat dorsal root ganglion (20 um). The tissues was from perfusion fixed animals with 4% PFA and later postfixed overnight in the same fixative. They were cryoprotected in 30% sucrose and cut using a cryostat.
