Product Use: Western blotting | Immunohistochemistry | ICC/Immunofluorescence

Antibody Dilution Recommended: WB (1:1000); optimal dilutions for assays should be determined by the user.

Antibody Potency: In mouse brain lysates, this antibody detects a ~50 kDa protein by Western blotting.

Antibody Species Reactivity: Mouse | Rat

Antibody Positive Control: 1 µg/ml of SMC-473 was sufficient for detection of TASK1 Potassium Channel in 20 µg of rat brain lysate by colorimetric immunoblot analysis using Goat anti-mouse IgG:HRP as the secondary antibody.

Antibody Specificity: Very high
Antibody Cross Reactivity: Does not cross-react with TASK3.

Scientific Background: K+ channels are divided into three subclasses reflecting the number of transmembrane segments (TMS), which are designated 6TMS, 4TMS and 2TMS. Members of the 4TMS class contain two distinct pore regions and include TWIK, TREK, TRAAK and TASK. TASK channels are highly sensitive to external pH in the physiological range. TASK-1 is expressed in brain and in rat heart, with high levels of expression in the right atrium. TASK-2, mainly expressed in kidney, is localized in cortical distal tubules and collecting ducts, suggesting a role in renal K+ transport. TASK-3 from rat cerebellum shares 54% identity with TASK-1, but less than 30% identity with TASK-2 and other tandem pore K+ channels.
