Introduction
IL23 is composed of a subunit of the heterodimeric cytokine IL23 and the p40 subunit of interleukin 12 (IL12B). Interleukin-23 (IL-23) belongs to the IL-12 family and is produced by antigen presenting cells. IL-23 using IL12RB1 and IL-23R (specific for IL-23) can activate STAT and NF-kB pathways and stimulate the production of interferon-gamma. ). IL-23 is known to take a vital part in the inflammation process and is associated with auto immune diseases. However, unlike IL12, which acts primarily on naive CD4(+) T cells, IL23 preferentially acts on memory CD4(+) T cells.
Description
Recombinant Human Interleukin-23 produced in Sf9 Baculovirus cells is a glycosylated heterodimer composed of 2 disulfide-linked subunits. A p19 subunit which is unique to IL23 and a p40 subunit which is shared with IL12. The p19 subunit/IL23A (20-189aa, total of 176 aa, MW 19.5kDa) and p40 subunit /IL12B (23-328aa, total of 306 aa, MW 34.6kDa), the total predicted molecular mass of 54.1kDa (Molecular weight on SDS-PAGE will appear higher). IL23 is fused to a 6 aa His-Tag at C-terminus and purified by proprietary chromatographic techniques.
