Our Abpromise guarantee covers the use of ab47099 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 at an assay dependent concentration.
ELISA Use at an assay dependent concentration.
IP Use at an assay dependent concentration.
WB Use a concentration of 1 µg/ml. Detects a band of approximately 14 kDa (predicted molecular weight: 19 kDa).


  • Function
    Might act as an inhibitor of spontaneous calcium carbonate precipitation. May be associated with neuronal sprouting in brain, and with brain and pancreas regeneration.
  • Tissue specificity
    In pancreatic acinar cells and, in lower levels, in brain. Enhanced expression of PSP-related transcripts and intraneuronal accumulation of PSP-like proteins is found in brain from Alzheimer disease and Down syndrome patients.
  • Sequence similarities
    Contains 1 C-type lectin domain.
  • Developmental stage
    High expression levels in fetal and infant brains; much lower in adult brains.
  • Post-translational
    The composition of the O-linked carbohydrate on Thr-27 is complex and varied. In the crystallographic structure, the attached sugar appears to be N-acetylglucosamine, typical of an intracellular protein, rather than N-acetylgalactosamine.

  • Anti-REG1 alpha antibody (ab47099) at 1 µg/ml + Human pancreas tissue lysate - total protein (ab29816) at 10 µg

    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 19 kDa

    Exposure time: 30 seconds

    The band observed at 14 kDa could potentially be a cleaved form of REG1 alpha due to the presence of a 25 amino acid signal peptide.
