Application Abreviews Notes
IHC-P 1/1000 - 1/2000. Perform heat mediated antigen retrieval before commencing with IHC staining protocol. Citrate Buffer (pH 6.0)
Flow Cyt Use at an assay dependent concentration. PubMed: 25269858ab171870-Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.
IHC-Fr Use at an assay dependent concentration. PubMed: 20515941Slides were fixed in acetone for 20 minutes.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 55 kDa (predicted molecular weight: 49.7 kDa).Can be blocked with Recombinant Human RND1 protein (ab109840).


  • FunctionReversible 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 specificityExpressed 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 similaritiesBelongs to the alpha-carbonic anhydrase family.
    Contains 1 alpha-carbonic anhydrase domain.
  • Post-translational
    Asn-346 bears high-mannose type glycan structures.
  • Cellular localizationNucleus. Nucleus, nucleolus. Cell membrane. Cell projection, microvillus membrane. Found on the surface microvilli and in the nucleus, particularly in nucleolus.

  • Formalin fixed paraffin embedded renal carcinoma tissue, positively stained using Ab15086.
  • 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.
