ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.



  • Function
    Hyperpolarization-activated ion channel exhibiting weak selectivity for potassium over sodium ions. Contributes to the native pacemaker currents in heart (If) and in neurons (Ih). Activated by cAMP, and at 10-100 times higher concentrations, also by cGMP. May mediate responses to sour stimuli.
  • Tissue specificity
    Detected in brain, in particular in amygdala and hippocampus, while expression in caudate nucleus, corpus callosum, substantia nigra, subthalamic nucleus and thalamus is very low or not detectable. Detected at very low levels in muscle and pancreas.
  • Sequence similarities
    Belongs to the potassium channel HCN family.
    Contains 1 cyclic nucleotide-binding domain.
  • Domain
    The segment S4 is probably the voltage-sensor and is characterized by a series of positively charged amino acids at every third position.

  • ab84816 staining HCN1 in human hippocampal tissue by IHC-P (Bouin's fixed paraffin embedded).
  • Anti-HCN1 antibody [N70/28] (ab84816) + rat brain lysate

    Predicted band size: 99 kDa
    Observed band size: 99 kDa

    As secondary antibody a goat anti-mouse IgG conjugated with HRP was used.
  • Overlay histogram showing SH-SY5Y cells stained with ab84816 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab84816, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive result in SH-SY5Y cells fixed with 4% paraformaldehyde (10 min)/permeabilized in 0.1% PBS-Tween for 20 min used under the same conditions.

  • Immunohistochemical analysis of murine cochlear tissue, staining HCN1 (red) with ab84816.

    Tissue was permeabilized with 0.3% Triton X-100 before being blocked with goat serum. Sections were incubated with primary antibody (1/100) overnight at 4°C. An AlexaFluor®568-conjugated goat anti-mouse IgG (1/2000) was used as the secondary antibody.
