• Product name
  • Description
    Rabbit polyclonal to Skp1
  • Host species
  • Specificity
    This antibody detects a 19kD band in Hela and HEK293 cells. The band can be blocked with the immunising peptide. The antibody shows extensive staining (eg. of lymphoid and epithelial cells), with staining of nuclei and some staining of the cytoplasm, when tested on human tonsil in IHC.
  • Tested applications
    Suitable for: WB, IHC-P, ICC/IFmore details

  • Positive control
    • Recombinant Human Skp1 protein (ab117211) can be used as a positive control in WB. This antibody gave a positive signal in HeLa nuclear lysate as well as the following whole cell lysates: HeLa; HEK293. IF/ICC: MCF7 cell line



Our Abpromise guarantee covers the use of ab10546 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 1/500. Detects a band of approximately 19 kDa (predicted molecular weight: 18.5 kDa).
IHC-P Use at an assay dependent concentration.
ICC/IF Use a concentration of 1 µg/ml.


  • Function
    Essential component of the SCF (SKP1-CUL1-F-box protein) ubiquitin ligase complex, which mediates the ubiquitination of proteins involved in cell cycle progression, signal transduction and transcription. In the SCF complex, serves as an adapter that links the F-box protein to CUL1. SCF(BTRC) mediates the ubiquitination of NFKBIA at 'Lys-21' and 'Lys-22'; the degradation frees the associated NFKB1-RELA dimer to translocate into the nucleus and to activate transcription. SCF(Cyclin F) directs ubiquitination of CP110.
  • Pathway
    Protein modification; protein ubiquitination.
  • Sequence similarities
    Belongs to the SKP1 family.

    Secondary ab: Goat anti-rabbit IgG ab6721 (1/5000)
    Exposure time: 2 mins.

  • ICC/IF image of ab10546 stained MCF7 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 (ab10546, 1µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 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.

  • ab10546 was used in immunohistochemistry with paraffin embedded sections of human tonsil, using DAB as a chromogen (brown). Counterstaining of nuclei was performed with haemotoxylin (blue).
    Strong staining of epithelial cell nuclei is seen (and some staining of the cytoplasm) in this image.
