Kir2.1 (KCNJ2) Antibody (MA5-45416) in ICC/IF
Immunocytochemistry/Immunofluorescence analysis using human neuroblastoma cells. Fixation involved 4% PFA for 15 min. Samples were incubated with Kir2.1 monoclonal antibody (Product # MA5-45416) at 1:50 for overnight at 4°C with slow rocking, followed by AlexaFluor 488 at 1:1,000 for 1 hour at RT. Counterstain used was Phalloidin-iFluor 647 (red) F-Actin stain; Hoechst (blue) nuclear stain at 1:800, 1.6mM f... View More

Product Specific Information
1 µg/mL of MA5-45416 was sufficient for detection of Kir2.1 in 10 µg of rat brain lysate by colorimetric immunoblot analysis using Goat anti-mouse IgG:HRP as the secondary antibody.|Detects approximately 45kDa. No cross-reactivity against Kir2.2 or Kir2.3.
Target Information
The KIR2 subunit family includes 2. 1, 2. 2, 2. 3 and 2. 4. Unlike G protein-coupled KIR3 subunits, KIR2. 1 requires both phosphorylation by PKA and ATP hydrolysis for functional activity. KIR2. 1 is expressed in the superior and inferior collicula and the pontine region of the brain, where it moderates synaptic transmission, like many other potassium channels. In the placenta, KIR2. 1 is expressed throughout gestation in cytotrophoblast cells. In the kidney, KIR2. 1 colocalizes with KIR5. 1 in the proximal tubule. KIR2. 1, 2. 2 and 2. 3 associate with the membrane-associated guanylate kinase synapseassociated protein 97 in the cerebellum and heart. Phosphorylation of KIR2. 2 by protein kinase A inhibits the associates with SAP97.
