ELISA Kit Principle | Aviva's human Eotaxin ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for Eotaxin has been precoated onto 96-well plates. Standards(E.coli, G24-P97) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for Eotaxin 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 Eotaxin amount of sample captured in plate. | |||||||||||||||||||||||||||||||||||

:: | Principle: Aviva’s human Eotaxin ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. Human Eotaxin 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 Eotaxin 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: Eotaxin, also known as CCL11, is a potent inducer of eosinophil chemotaxis and is considered as a selective ligand of the CC chemokine receptor 3 (CCR3), which is expressed on eosinophils, basophils, and Th2 lymphocytes.1 Eotaxin is assumed to be involved in eosinophilic inflammatory diseases such as atopic dermatitis, allergic rhinitis, asthma and parasitic infections.2 The gene maps to chromosome 17 and is expressed constitutively at high levels in small intestine and colon, and at lower levels in various other tissues. The deduced mature protein sequence is 66% identical to human monocyte chemoattractant protein-1, and 60% identical to guinea pig eotaxin. Recombinant human eotaxin produced in insect cells induces a calcium flux response in normal human eosinophils, but not in neutrophils or monocytes.3 The human eotaxin gene is cloned and found to be 61.8 and 63.2% identical at the amino acid level to guinea pig and mouse eotaxin.4 | |||||||||||||||||||||||||||||||||||
