Product Description
EliKine™ Rat IL-4 ELISA Kit | KET9003 | Abbkine
Application: EliKine™ Rat IL-4 ELISA Kit employs a two-site sandwich ELISA to quantitate IL-4 in samples. An antibody specific for IL-4 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and any IL-4 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for IL-4 is added to the wells. After washing, proprietary EliKine™ Streptavidin-HRP conjugates is added to the wells. Following a wash to remove any unbound streptavidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of IL-4 bound in the initial step. The color development is stopped and the intensity of the color is measured.

Usage Note: • Do not mix components from different kit lots or use reagents beyond the kit expiration date.
• Allow all reagents to warm to room temperature for at least 30 minutes before opening.
• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.
• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
• It is recommended that all samples and standards be assayed in duplicate or triplicate.
Storage Instruction: The unopened kit should be stored at 2 - 8°C. After opening, please store refer to protocols.
Shipping: Gel pack with blue ice.

Background: Interleukin 4 is a pleiotropic cytokine produced primarily by activated T lymphocytes, mast cells and basophils . IL-4 has multiple immune response-modulating functions on a variety of cell types. It is an important modulator of the differentiation of precursor T helper cells to the Th2 subset that mediates humoral immunity and modulates antibody production. In addition, IL-4 has also been shown to have anti-tumor activity both in vivoand in vitro.The biological effects of IL-4 are mediated by specific cell surface receptor complexes. One type of functional IL-4 receptor complex consists of the IL-4-binding subunit and a second chain, designated the common c chain because it has also been identified as a component of the receptor complexes for IL-4, IL-7, IL-9 and IL-15
