Our Abpromise guarantee covers the use of ab83291 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
IHC-P Use a concentration of 4 - 8 µg/ml.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 73 kDa (predicted molecular weight: 73 kDa).Can be blocked with Human KHSRP peptide (ab111652). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
ICC/IF Use a concentration of 5 µg/ml.


  • FunctionBinds to the dendritic targeting element and may play a role in mRNA trafficking (By similarity). Part of a ternary complex that binds to the downstream control sequence (DCS) of the pre-mRNA. Mediates exon inclusion in transcripts that are subject to tissue-specific alternative splicing. May interact with single-stranded DNA from the far-upstream element (FUSE). May activate gene expression. Also involved in degradation of inherently unstable mRNAs that contain AU-rich elements (AREs) in their 3'-UTR, possibly by recruiting degradation machinery to ARE-containing mRNAs.
  • Tissue specificityDetected in neural and non-neural cell lines.
  • Sequence similaritiesBelongs to the KHSRP family.
    Contains 4 KH domains.
  • Post-translational
    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localizationNucleus. Cytoplasm. A small proportion is also found in the cytoplasm of neuronal cell bodies and dendrites.

  • ICC/IF image of ab83291 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 (ab83291, 5µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit 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.
