Pepinh-TRIF

TRIF inhibitory peptide

Pepinh-TRIF is a 30 aa peptide that blocks TRIF signaling by interfering with TLR-TRIF interaction.

PepinhTRIF contains the 14 aa that correspond to the sequence of the BB loop of TRIF (FCEEFQVPGRGELH) [1] linked to the cell-penetrating segment of the antennapedia homoedomain (RQIKIWFQNRRMKWKK) [2].

Pepinh TRIF is provided with Pepinh-Control, a control peptide [1].
