Application

Staphylococcal enterotoxin B (SEB) which binds to MHC class II molecules and specific Vβ regions of T cell receptors (TCR), resulting in the activation of both monocytes/macrophages and T lymphocytes may be used as a superantigen and immune system activator. SEB may be used as a reference material in the development of SEB detection systems.

Biochem/physiol Actions

A superantigen for T-lymphocytes. Activator of the immune system that binds to major histocompatibility complex (MHC) antigens and CD28.
