Our Abpromise guarantee covers the use of ab81086 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 0.1 - 1 µg/ml. Detects a band of approximately 60 kDa (predicted molecular weight: 55 kDa).
ELISA Use a concentration of 0.01 - 0.1 µg/ml.
Flow Cyt Use a concentration of 2 - 5 µg/ml. ab171870-Rabbit polyclonal IgG, is suitable for use as an isotype control with this antibody.
IHC-P Use a concentration of 2 - 5 µg/ml.


  • FunctionTranscriptional activator that binds to DNA sequences containing the consensus pentanucleotide 5'-CGGA[AT]-3'.
  • Tissue specificityVery highly expressed in brain, highly expressed in testis, lung and heart, moderately in spleen, small intestine, pancreas and colon, weakly in liver, prostate and thymus, very weakly in skeletal muscle, kidney and ovary and not in placenta and peripheral blood leukocytes.
  • Involvement in diseaseDefects in ETV1 are a cause of Ewing sarcoma (ES) [MIM:612219]. A highly malignant, metastatic, primitive small round cell tumor of bone and soft tissue that affects children and adolescents. It belongs to the Ewing sarcoma family of tumors, a group of morphologically heterogeneous neoplasms that share the same cytogenetic features. They are considered neural tumors derived from cells of the neural crest. Ewing sarcoma represents the less differentiated form of the tumors. Note=A chromosomal aberration involving ETV1 is found in patients with Erwing sarcoma. Translocation t(7;22)(p22;q12) with EWSR1.
  • Sequence similaritiesBelongs to the ETS family.
    Contains 1 ETS DNA-binding domain.

  • All lanes : Anti-ER81 antibody (ab81086) at 1/500 dilution

    Lane 1 : Tissue lysate derived from mouse brain
    Lane 2 : Tissue lysate derived from mouse brain, pre-incubated with immunizing peptide

    Predicted band size : 55 kDa
    Observed band size : 60 kDa (why is the actual band size different from the predicted?)
  • ab81086 (4µg/ml) staining ER81 in human testis using an automated system (DAKO Autostainer Plus). Using this protocol there is strong nuclear staining of seminal vesicles.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer citrate pH 6.1 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako envision flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
