  • General notes

    Ab239838 is the carrier-free version of ab51023. This format is designed for use in antibody labeling, including fluorochromes, metal isotopes, oligonucleotides, enzymes.


    Our carrier-free formats are supplied in a buffer free of BSA, sodium azide and glycerol for higher conjugation efficiency.

    Use our conjugation kits  for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.

    ab239838 is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm.

    Maxpar® is a trademark of Fluidigm Canada Inc.

    Our RabMAb® technology is a patented hybridoma-based technology for making rabbit monoclonal antibodies. For details on our patents, please refer to RabMab® patents.

    This product is a recombinant rabbit monoclonal antibody.



Our Abpromise guarantee covers the use of ab239838 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
Flow Cyt Use at an assay dependent concentration.

ab199376 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.

ICC/IF Use at an assay dependent concentration.
IP Use at an assay dependent concentration.
WB Use at an assay dependent concentration. Detects a band of approximately 36 kDa (predicted molecular weight: 43 kDa).
  • Application notes
    Is unsuitable for IHC-P.
  • Target

    • Function

      NAD-dependent protein deacetylase, which deacetylates the 'Lys-40' of alpha-tubulin. Involved in the control of mitotic exit in the cell cycle, probably via its role in the regulation of cytoskeleton.
    • Tissue specificity

      Widely expressed. Highly expressed in heart, brain and skeletal muscle, while it is weakly expressed in placenta and lung. Down-regulated in many gliomas suggesting that it may act as a tumor suppressor gene in human gliomas possibly through the regulation of microtubule network.
    • Sequence similarities

      Belongs to the sirtuin family.
      Contains 1 deacetylase sirtuin-type domain.
    • Developmental stage

      Peaks during mitosis. After mitosis, it is probably degraded by the 26S proteasome.
    • Post-translational

      Phosphorylated at the G2/M transition of the cell cycle.
    • Cellular localization

      Cytoplasm > cytoskeleton. Colocalizes with microtubules.

    • Immunofluorescence staining of PC-12 cells using ab51023 (green) at a dilution of 1/250. The cells were fixed in 4% PFA and counter stained with an anti-tubulin antibody (red) and DAPI (blue).

      This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab51023).

    • Flow cytometry analysis of permeabilized Hela cells using anti-SIR2/SIRT2 (red)(ab51023) or a rabbit IgG (negative)(green).

      This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab51023).
