Our Abpromise guarantee covers the use of ab232941 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 1/5000. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


It is recommended to perform standard protocol F with the peroxidase block step moved in between the polymer and DAB incubation on a Leica BONDTM system. Using standard protocol F on Leica BONDTM system is likely to cause higher background with ab232941. 


  • Function

    Receptor for the CD200/OX2 cell surface glycoprotein. Also binds to HHV-8 K14 viral CD200 homolog with identical affinity and kinetics as the host CD200.
  • Tissue specificity

    Expressed in granulocytes, monocytes, most T cells, neutrophils, basophils and a subset of NK, NKT and B cells (at protein level). Expressed in bone marrow, lymph nodes, spleen, lung, liver, spinal cord, kidney. Expressed in monocyte-derived dendritic and mast cells.
  • Sequence similarities

    Belongs to the CD200R family.
    Contains 1 Ig-like C2-type (immunoglobulin-like) domain.
    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Post-translational

    The mature form of isoform 2 and/or isoform 4 starts at sequence position 27 of the corresponding isoform.
  • Cellular localization

    Secreted and Cell membrane.

  • IHC image of CD200R1 staining in a section of formalin-fixed paraffin-embedded normal human tonsil and human normal skeletal muscle* performed on a Leica BONDTM system using the standard protocol F with the peroxidase block step moved in between the polymer and DAB incubation. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20mins. The section was then incubated with ab232941 at 0.1µg/ml for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX. The inset secondary-only control image is taken from an identical assay without primary antibody.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
