  • General notes

    ab239595 is a PBS-only buffer format of ab61400. Please refer to ab61400 for recommended dilutions, protocols, and image data.

    This antibody clone is manufactured by Abcam. If you require a custom buffer formulation or conjugation for your experiments, please contact orders@abcam.com.

    In mouse CD38 is expressed by follicular B cells, is down regulated on germinal centre B cells, and not expressed by mature plasma cells. This pattern of expression contrasts strikingly with that seen in the human.


Our Abpromise guarantee covers the use of ab239595 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Flow Cyt Use at an assay dependent concentration.


  • Function
    Synthesizes cyclic ADP-ribose, a second messenger for glucose-induced insulin secretion. Also has cADPr hydrolase activity. Also moonlights as a receptor in cells of the immune system.
  • Tissue specificity
    Expressed at high levels in pancreas, liver, kidney, brain, testis, ovary, placenta, malignant lymphoma and neuroblastoma.
  • Sequence similarities
    Belongs to the ADP-ribosyl cyclase family.
  • Developmental stage
    Preferentially expressed at both early and late stages of the B and T-cell maturation. It is also detected on erythroid and myeloid progenitors in bone marrow, where the level of surface expression was shown to decrease during differentiation of blast-forming unit E to colony-forming unit E.

  • C57BL/6 mouse splenocytes stained with ab61400 (right) or Rat IgG2aΚ (monoclonal) (left). C57BL/6 Mouse splenocytes were incubated for 30 min on ice in 1x PBS containing 10 µg/ml anti CD16/32 antibody and 10% normal goat serum to block FC receptors and non-specific protein-protein interactions followed by the antibody (ab61400) or Rat IgG2a Isotype (1x106 in 100µl at 1 µg/ml) (left) for 30 min on ice.

    The secondary antibody Goat anti-rat IgG H&L (Alexa Fluor® 488, pre-adsorbed) (ab150165) was used at 1/2000 dilution for 30 min at 4°. The cells were simultaneously stained with CD19 APC conjugated antibody.

    Acquisition of >50,000 events were collected using a 50 mW Blue laser (488nm) and 530/30 bandpass filter. Events were gated on viable lymphocytes.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS and sodium azide (ab61400).
