Application

Lipopolysaccharides from Salmonella typhosa are used in cell culture and cell binding applications. The role of LPS in the secretion of TNF-α and IL-6 was studied in mouse spleen cell culture. It was used to study the role of inflammatory responses in multiple sclerosis.
Lipopolysaccharides (LPSs) are characteristic components of the cell wall of Gram-negative bacteria. LPS and its lipid A moiety stimulate cells of the innate immune system by the Toll-like receptor 4 (TLR4), a member of the Toll-like receptor protein family, which recognizes common pathogen-associated molecular-patterns (PAMPs).

STAT2 is the quintessential transcription factor for type 1 interferons (IFNs), where it functions as a heterodimer with STAT1. However, the human and murine STAT2-deficient phenotypes suggest important additional and currently unidentified type 1 IFN-independent activities. Here, we show that
