Our Abpromise guarantee covers the use of ab52600 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 1/100000. Detects a band of approximately 60 kDa (predicted molecular weight: 51 kDa).
IP 1/50.
IHC-P Use at an assay dependent concentration.
ICC/IF 1/100 - 1/250.


  • FunctionOne of the major pre-mRNA-binding proteins. Binds tenaciously to poly(C) sequences. Likely to play a role in the nuclear metabolism of hnRNAs, particularly for pre-mRNAs that contain cytidine-rich sequences. Can also bind poly(C) single-stranded DNA.
  • Sequence similaritiesContains 3 KH domains.
  • Post-translational
    Arg-296 and Arg-299 are dimethylated, probably to asymmetric dimethylarginine.
  • Cellular localizationCytoplasm. Nucleus > nucleoplasm. In case of ASFV infection, there is a shift in the localization which becomes predominantly nuclear.

    HRP-labelled goat anti-rabbit at 1/2000 dilution

    Predicted band size : 51 kDa
    Observed band size : ~60 kDa (why is the actual band size different from the predicted?)
  • Immunohistochemical staining of paraffin-embedded human breast carcinoma tissue using ab52600 at a dilution of 1/100-1/250.
  • Fluorescent immunostaining of HeLa cells using ab52600 at a dilution of 1/100-1/250.
  • ab52600 at 1/100 immunoprecipitating hnRNP K in HeLa whole cell lysate.

    For western blotting, a primary antibody was used at 1/1000 and a HRP-conjugated goat-anti-rabbit IgG was used as the secondary antibody (1/1000).

    Blocking buffer and concentration: 5% NFDM/TBST.

    Diluting buffer and concentration: 5% NFDM /TBST.
