| ELISA Kit Principle | Aviva's human Fractalkine ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for Fractalkine has been precoated onto 96-well plates. Standards(NS0, Q25-R339) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Fractalkine is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The absorbance of yellow is proportional to the human Fractalkine amount of sample captured in plate. | |||||||||||||||||||||||||||||||||||

| :: | Principle: Aviva’s human Fractalkine ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. Human Fractalkine specific-specific polyclonal antibodies were precoated onto 96-well plates. The human specific detection polyclonal antibodies were biotinylated. The test samples and biotinylated detection antibodies were added to the wells subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with PBS or TBS buffer. HRP substrate TMB was used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the human Fractalkine amount of sample captured in plate. | |||||||||||||||||||||||||||||||||||
| :: | Notes: 1. To inspect the validity of experiment operation and the appropriateness of sample dilution proportion, pilot experiment using standards and a small number of samples is recommended. 2. The TMB Color Developing agent is colorless and transparent before using, contact us freely if it is not the case. 3. Before using the Kit, spin tubes and bring down all components to the bottom of tubes. 4. Duplicate well assay is recommended for both standard and sample testing. 5. Don’t let 96-well plate dry, for dry plate will inactivate active components on plate. 6. Don’t reuse tips and tubes to avoid cross contamination. 7. To avoid to use the reagents from different batches together. 8. In order to avoid marginal effect of plate incubation due to temperature difference ( reaction may be stronger in the marginal wells), it is suggested that the diluted ABC and TMB solution will be pre-warmed in 37C for 30 min before using. Background: Chemokine (C-X3-C motif) ligand 1 (CX3CL1) is a large cytokine protein of 373 amino acids, it contains multiple domains and is the only known member of the CX3C chemokine family. It is also commonly known under the names fractalkine (in humans) and neurotactin (in mice).1, 2 CX3CL1 is produced as a long protein (with 373-amino acid in humans) with an extended mucin-like stalk and a chemokine domain on top. The mucin-like stalk permits it to bind to the surface of certain cells. However a soluble (90 kD) version of this chemokine has also been observed. Soluble CX3CL1 potently chemoattracts T cells and monocytes, while the cell-bound chemokine promotes strong adhesion of leukocytes to activated endothelial cells, where it is primarily expressed.2 CX3CL1 elicits its adhesive and migratory functions by interacting with the chemokine receptor CX3CR1.3 Its gene is located on human chromosome 16 along with some CC chemokines known as CCL17 and CCL22.2, 4 It can act as a mediator of smooth muscle cell migration in human atherosclerosis, rather than mediate inflammatory cell recruitment.5 The standard product used in this kit is recombinant human CX3CL1, consisting of 76 amino acids with the molecular mass of 8.5kDa. | |||||||||||||||||||||||||||||||||||
