ELISA Kit Principle | Aviva's human IL-4 ELISA Kit was based on standard sandwich enzyme-linked immune-sorbent assay technology. A monoclonal antibody from mouse specific for IL-4 has been precoated onto 96-well plates. Standards(E.coli, H25-S153) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for IL-4 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 IL-4 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: nterleukin-4 (IL-4), also knowns as a B-cell stimulatory factor1 (BSF1), is an immunomodulatory cytokine, which can inhibit the growth of tumour cells.The human cDNA contains a single open reading frame encoding a protein of 153 amino acids, including a putative signal peptide. IL-4 may act as an autocrine growth factor in pancreatic cancer cells and also give rise to the possibility that cancer-derived IL-4 may suppress cancer-directed immunosurveillance in vivo in addition to its growth-promoting effects, thereby facilitating pancreatic tumor growth and metastasis. The mouse and human genes and their protein products show structural and functional similarities. The human IL-4 gene, which occurs as a single copy in the haploid genome, is mapped on chromosome 5.The standard product used in this kit is recombinant human IL-4, consisting of 130 amino acids with the molecular mass of 14KDa. | |||||||||||||||||||||||||||||||||||
