Detection of Human IL‑12 R beta 2 by Western Blot.

Western blot shows lysates of human CD4+in vitrodifferentiated Th1 cells. PVDF Membrane was probed with 2 µg/mL of Mouse Anti-Human IL-12 R beta 2 Monoclonal Antibody (Catalog # MAB19591) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for IL-12 R beta 2 at approximately 80 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: IL-12 R beta 2

IL-12 R beta 2 is a type I cytokine receptor family protein that associates with IL 12 R beta 1 to form a functional high affinity receptor complex for IL-12. The extracellular region of IL 12 R beta 2 contains five fibronectin type 3 domains. The cytoplasmic region is alternatively spliced, giving rise to two isoforms. IL-12 R beta 2 is up‑regulated in Th1 cells during inflammatory responses. The extracellular regions of human and mouse IL‑12 R beta 2 share 69% amino acid sequence identity.
