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.

Recovery
The recovery of Fractalkine spiked to three different levels throughout the range of the assay in various matrices was evaluated.
| Sample Type | Average % Recovery | Range % |
| Serum (n=4) | 99 | 88-111 |
| Heparin Plasma (n=4) | 97 | 85-108 |
| EDTA Plasma (n=4) | 101 | 88-113 |
| Urine (n=4) | 96 | 86-109 |
| Cell Culture Media (n=4) | 98 | 93-102 |

Linearity
To assess the linearity of the assay, samples containing or spiked with high concentrations of Fractalkine were diluted with the appropriate Calibrator Diluent to produce samples with values within the dynamic range of the assay.

- CX3CL1/Fractalkine
- Aliases
- FKN; Fractalkine; Neurotactin
- Entrez Gene IDs
- 6376 (Human); 20312 (Mouse); 89808 (Rat)
- Background
- CX3CL1/Fractalkine
- Fractalkine, also named neurotactin, is a chemokine identified through bioinformatics. Fractalkine has a unique CX3C cysteine motif near the amino-terminus and is the one member of a fourth branch of the chemokine superfamily. The extracellular domain of human Fractalkine can be released by proteolysis, at the dibasic cleavage site proximal to the membrane to generate soluble fractalkine.
