Product Information

KE00235 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The IL-28B ELISA kit is to be used to detect and quantify protein levels of endogenous IL-28B. The assay recognizes human IL-28B. An antibody specific for IL-28B has been pre-coated onto the microwells. The IL-28B protein in samples is captured by the coated antibody after incubation. Following extensive washing, another horseradish peroxidase (HRP)-conjugated antibody specific for IL-28B is added to detect the captured IL-28B protein. For signal development, followed by Tetramethyl-benzidine (TMB) reagent. Solution containing sulfuric acid is used to stop color development and the color intensity which is proportional to the quantity of bound protein is measurable at 450 nm with the correction wavelength set at 630 nm.

Background Information

IL-28B, also named as IFNL3, is a cytokine distantly related to type I interferons and the IL-10 family. IL-28B, interleukin 28A (IL-28A), and interleukin 29 (IL-29) are three closely related cytokine genes that form a cytokine gene cluster on a chromosomal region mapped to 19q13. Expression of the cytokines encoded by the three genes can be induced by viral infection. All three cytokines have been shown to interact with a heterodimeric class II cytokine receptor that consists of interleukin 10 receptor, beta (IL-10RB) and interleukin 28 receptor, alpha (IL-28RA). IL-28B was identified as a key regulator of B- and T-cell vaccine responses against influenza.
