Product Summary

The Quantikine Human Fractalkine immunoassay is a 4.5 hour solid phase ELISA designed to measure Fractalkine in cell culture supernates, serum, plasma, saliva, urine, and human milk. It contains NS0-expressed recombinant human Fractalkine and has been shown to accurately quantitate the recombinant factor. Results obtained using natural Fractalkine showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human Fractalkine.

Precision

Intra-Assay Precision (Precision within an assay) Three samples of known concentration were tested on one plate to assess intra-assay precision
Inter-Assay Precision (Precision between assays) Three samples of known concentration were tested in separate assays to assess inter-assay precision

Background: CX3CL1/Fractalkine

CX3CL1/Fractalkine is a transmembrane adhesion protein with a chemokine domain separated from the membrane by a mucin stalk. It is upregulated on many cell types during inflammation. The chemokine and mucin regions can be shed as a soluble chemokine that signals through the receptor CX3CR1. During extravasation, membrane-bound CX3CL1 traps leukocytes, then is cleaved to allow diapedesis. Soluble CX3CL1 protects neurons from microglial neurotoxicity, recruits macrophages for wound healing, recruits osteoclast precursors for bone resorption, and contributes to pathogenesis in coronary artery disease.

    3. 100 µL Assay Diluent
  3.   Add 100 µL of Assay Diluent to each well.
    4. 100 µL Standard, Control, or Sample
  4.   Add 100 µL of Standard, control, or sample to each well within 15 minutes. Cover with a plate sealer, and incubate at 2-8 °C for 3 hours.
  5.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
    6. 200 µL cold Conjugate
  6.   Add 200 µL of cold Conjugate to each well. Cover with a new plate sealer, and incubate at 2-8 °C for 1 hour.
  7.   Aspirate and wash 4 times.
    8. 200 µL Substrate Solution
  8.   Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.
    9. 50 µL Stop Solution
  9.   Add 50 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
