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

Application Abreviews Notes
Blocking Use at an assay dependent dilution.
IHC-P Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ELISA Use a concentration of 0.5 µg/ml.
WB Use a concentration of 0.1 - 0.2 µg/ml.


  • Function

    The soluble form is chemotactic for T-cells and monocytes, but not for neutrophils. The membrane-bound form promotes adhesion of those leukocytes to endothelial cells. May play a role in regulating leukocyte adhesion and migration processes at the endothelium. Binds to CX3CR1.
  • Tissue specificity

    Small intestine, colon, testis, prostate, heart, brain, lung, skeletal muscle, kidney and pancreas.
  • Sequence similarities

    Belongs to the intercrine delta family.
  • Post-translational

    A soluble short 95 kDa form may be released by proteolytic cleavage from the long membrane-anchored form.
    O-glycosylated with core 1 or possibly core 8 glycans.
  • Cellular localization

    Secreted and Cell membrane.

  • IHC image of CX3CL1 staining in human lung formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab9819, 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.

    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.

Customer reviews and Q&As


Thank you for your enquiry. ab9819 will recognize the chemokine domain of human Fractalkine (76 a.a.). The chemokine domain is amino acids 25-100 of the extracellular domain (25-341). The sequence of which is as follows: QHHGVTKCNI TCSKMTSKIP VALLIHYQQN QASCGKRAII LETRQHRLFC ADPKEQWVKD AMQHLDRQAA ALTRNG I hope this helps and if you have any further questions, please do not hesitate to contact me.
