Shield-1 is a specific, high-affinity and cell-permeant ligand of FK506-binding protein-12 (FKBP), and reverses the instability by binding to mutated FKBP (mtFKBP), allowing conditional expression of mtFKBP-fused proteins. Shield-1 can stabilize the entire fusion protein.

Myricetin-3-O-robinoside is a flavonoid isolated from cassava flowers by chromatographic techniques. Its structure consists of a myricetin backbone to which a robinose moiety is attached at the third position.

TLR1 is a cell-penetrating Toll/IL-1 receptor/resistance (TIR) domain/BB-Loop mimic and inhibits IL-1 receptor-mediated responses.
