  • Function
    Reversible hydration of carbon dioxide. Participates in pH regulation. May be involved in the control of cell proliferation and transformation. Appears to be a novel specific biomarker for a cervical neoplasia.
  • Tissue specificity
    Expressed primarily in carcinoma cells lines. Expression is restricted to very few normal tissues and the most abundant expression is found in the epithelial cells of gastric mucosa.
  • Sequence similarities
    Belongs to the alpha-carbonic anhydrase family.
    Contains 1 alpha-carbonic anhydrase domain.
  • Post-translational
    Asn-346 bears high-mannose type glycan structures.
  • Cellular localization
    Nucleus. Nucleus, nucleolus. Cell membrane. Cell projection, microvillus membrane. Found on the surface microvilli and in the nucleus, particularly in nucleolus.

    Goat polyclonal to Rabbit IgG - H&L - Pre-Adsorbed (HRP) at 1/3000 dilution

    Predicted band size : 49.7 kDa
    Observed band size : 55 kDa (why is the actual band size different from the predicted?)
  • ab15086 at 1/500 staining dog gastric mucosa tissue sections by IHC-P. The tissue was formaldehyde fixed and a standard citrate buffer was used for anitgen retrieval. The tissue was blocked with 10% serum prior to incubation with the antibody for 15 hours. A biotinylated donkey anti-rabbit IgG (H + L) was used as the secondary.

Thank you for contacting us.

We have several HIF antibodies in our catalog that react with mouse. For example, ab8366: HIF1 alpha, ab199: HIF2 alpha, ab10134: HIF3 alpha, ab465: HIF1 beta. If you could let me know which HIF you are looking fo...
