Other Product Data

Note: FSL-1 stimulation induces a MyD88-dependent signaling cascade leading to the activation of NF-κB and the production of proinflammatory cytokines. FSL-1 exhibits a higher stimulatory activity than MALP-2 when tested for its ability to induce the production of TNF-α in macrophages and NF-κB in TLR2/TLR6 transfected HEK293 cells. Depending on the sensitivity of the in vitro assay, the recommended working concentration for specific stimulation of innate immunity via TLR2/TLR6 heterodimers is 10-100nM. FSL-1 is water soluble in contrast to MALP2.

Description
  • R-FSL-1 (R-Pam2CGDPKHPKSF) is a synthetic lipoprotein that represents the N-terminal part of the 44kDa lipoprotein LP44 of Mycoplasma salivarium [1].
  • The naturally occurring R-stereoisomer is biologically more active than the S-stereoisomer [4].
  • Stimulator of TLR2/TLR6 [2-13].
  • Inducer of TNF-α production in macrophages [5].
  • Upregulates proinflammatory cytokines [3,5].
  • Activator of the proinflammatory transcription factor NF-κB [3].
