SPA4

Catalog No.: A36131
Active peptides
SPA4 is a Toll-like receptor 4 (TLR4)-interacting peptide that specifically inhibits the lipopolysaccharide (LPS)-induced production of the pro-inflammatory cytokine TNF-α. This compound demonstrates its biological activity without adversely affecting cell viability or size. SPA4 is useful in research applications related to inflammation, cytokine signaling, and TLR4-mediated pathways.
