Our Abpromise guarantee covers the use of ab47574 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
ICC/IF Use a concentration of 5 µg/ml.
WB 1/500 - 1/1000. Detects a band of approximately 54 kDa (predicted molecular weight: 54 kDa).
ELISA 1/60000.
IHC-P Use a concentration of 4 µg/ml.



  • All lanes : Anti-Chk1 antibody (ab47574) at 1/500 dilution

    Lane 1 : HT29 cell extract treated with UV. No peptide.
    Lane 2 : HT29 cell extract treated with UV. Synthetic peptide present.

    Predicted band size: 54 kDa
    Observed band size: 54 kDa

    Secondary antibody - anti-rabbit HRP (ab6721)

  • ab47574 staining Chk1 in Human heart.
    Left panel: with primary antibody at 4 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 buffers EDTA pH 9.0. 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 we recommend to optimize the primary antibody concentration and incubation time (overnight incubation), and amplification may be required.
  • ICC/IF image of ab47574 stained MCF-7 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab47574 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
