Product Description |
Recombinant Human IL-23 alpha&IL-12 beta Protein is expressed from HEK293 with His tag at the C-terminus.It contains Arg20-Pro189(IL-23 alpha) & Ile23-Ser328(IL-12 beta). |
Product Background |
The interleukin (IL)-12 family of cytokines, including IL12 and IL 23, play an important role in driving aberrant Th1 and Th17 immune responses in patients with Crohn's disease (CD). Targeting this pathway has opened new avenues for therapeutic intervention. The balance of proinflammatory cytokines interleukin (IL)-12 and IL-23 plays a key role in shaping the development of antitumor or protumor immunity. |

Amino Acid Range |
Arg20-Pro189(IL-23 alpha) & Ile23-Ser328(IL-12 beta) |
Molecular Weight |
The protein has a predicted MW of 19.77 kDa (IL-23 alpha) and 34.7 kDa (IL-12 beta). Due to glycosylation, the protein migrates to 23 kDa (IL-23 alpha) and 40-50 kDa (IL-12 beta) based on Bis-Tris PAGE result. |
