  • Product overview

    Rat Fractalkine in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of Fractalkine protein in rat serum, plasma and cell culture supernatant.


    The SimpleStep ELISA® employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.


    Fractalkine (CX3CL1 or Neurotactin) is a chemokine produced from a type I transmembrane protein on the cell surface. The soluble chemokine is generated by proteolytic cleavage and represents residues 25-100 of the full protein sequence. Fractalkine expression is primarily on epithelial cells. Fractalkine functions both in the full length transmembrane form (for adhesion) and in the released soluble form (chemoattraction).

  • Research areas

  • 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
    modifications

    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.

  • SimpleStep ELISA technology allows the formation of the antibody-antigen complex in one single step, reducing assay time to 90 minutes. Add samples or standards and antibody mix to wells all at once, incubate, wash, and add your final substrate. See protocol for a detailed step-by-step guide.

     

  • The Fractalkine standard curve was prepared as described in Section 10. Background-subtracted data values (mean +/- SD) are graphed.

  • The concentrations of Fractalkine were measured in duplicates, interpolated from the Fractalkine standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 100%, plasma (EDTA) 100%, plasma (heparin) 50% and plasma (citrate) 100%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Fractalkine concentration was determined to be 151 ng/mL in serum, 118 ng/mL in plasma (EDTA) 250 ng/mL in plasma (heparin), and 93 ng/mL in plasma (citrate).
