Target

Anti-ERK1 (phospho Y204) + ERK2 (phospho Y187) antibody images

  • All lanes : Anti-ERK1 (phospho Y204) + ERK2 (phospho Y187) antibody (ab47339) at 1/500 dilution

    Lane 1 : Extracts from Jurkat cells treated with PMA (200ng/ml, 15min)
    Lane 2 : Extracts from Jurkat cells un-treated


    Predicted band size : 44, 42 kDa
    Observed band size : 42,44 kDa
  • Ab47339 staining human normal or colon tissue. Staining is localised to cytoplasm.
    Left panel: with primary antibody at 2 ug/ml. Right panel: isotype control.
    Sections were stained using an automated system DAKO Autostainer Plus , at room temperature. Sections were rehydrated and antigen retrieved with the Dako 3-in-1 AR buffer EDTA pH 9.0 in a DAKO PT Link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 minutes. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 minutes 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 we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.
