β-Defensin-2 (human) (trifluoroacetate salt)

β-Defensin-2 is an antimicrobial peptide that provides innate immune defense for epithelial surfaces in the respiratory, gastrointestinal, and genitourinary tracts. It is widely used in research to study its inhibitory effects against oral pathogens like P. gingivalis and S. salivarius in both in vitro antimicrobial assays and in vivo models of infection and immunity.
