Application Abreviews Notes
WB 1/10000 - 1/200000. Detects a band of approximately 30 kDa (predicted molecular weight: 30 kDa).
IP 1/30.
IHC-P Use at an assay dependent concentration.
ICC/IF 1/100 - 1/250.
  • Application notesIs unsuitable for Flow Cyt.
  • Target

    • FunctionMay play an important role in controlling cell growth and proliferation through the selective translation of particular classes of mRNA.
    • Sequence similaritiesBelongs to the ribosomal protein S6e family.
    • Post-translational
      Ribosomal protein S6 is the major substrate of protein kinases in eukaryote ribosomes. The phosphorylation is stimulated by growth factors, tumor promoting agents, and mitogens. It is dephosphorylated at growth arrest.

    • ab80158 at 1/100-1/250 dilution staining RPS6 in human breast adenocarcinoma by Immunohistochemistry, Paraffin-embedded tissue.
    • ICC/IF image of ab80158 stained DU145 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 ab80158 at 1/200 dilution overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) 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.
