Our Abpromise guarantee covers the use of ab49333 in the following tested applications.

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

Application Abreviews Notes
WB Use a concentration of 2.5 µg/ml. Predicted molecular weight: 59 kDa.

Dilute in PBS or medium which is identical to that used in the assay system. At 100 nM, this antibody inhibits 50% of Factor XII activity. This antibody can also be used in a coagulation assay. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.

IHC-P Use a concentration of 4 - 8 µg/ml.


  • Function

    Cation channel with high affinity for sodium, which is gated by extracellular protons and inhibited by the diuretic amiloride. Generates a biphasic current with a fast inactivating and a slow sustained phase. In sensory neurons is proposed to mediate the pain induced by acidosis that occurs in ischemic, damaged or inflamed tissue. May be involved in hyperalgesia. May play a role in mechanoreception. Heteromeric channel assembly seems to modulate channel properties.
  • Tissue specificity

    Expressed by sensory neurons. Strongly expressed in brain, spinal chord, lung, lymph nodes, kidney, pituitary, heart and testis.
  • Sequence similarities

    Belongs to the amiloride-sensitive sodium channel (TC 1.A.6) family. ACCN3 subfamily.
  • Developmental stage

    Expressed in fetal tissues, expression increases in lung and kidney adult tissues.
  • Domain

    The PDZ domain-binding motif is involved in interaction with LIN7A, GOPC and MAGI1.
  • Post-translational

    Phosphorylated by PKA. Phosphorylated by PKC. In vitro, PRKCABP/PICK-1 is necessary for PKC phosphorylation and activation of a ACCN3/ASIC3-ACCN1/ASIC2b channel, but does not activate a homomeric ACCN3 channel.
  • Cellular localization

    Cell membrane. Cytoplasm. Cell surface expression may be stabilized by interaction with LIN7B and cytoplasmic retention by interaction with DLG4. In part cytoplasmic in cochlea cells.
