A 14-mer peptide (LQLDEETGEFLPIQ) conjugated to cell-penetrating trans-activating transcriptional activator (TAT) sequence (YGRKKRRQRRRLQ) that targets the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) binding site on Kelch-like ECH-associated protein 1 (Keap1). Competitively disrupts Nrf2-Keap1 interaction and stabilizes cytosolic Nrf2, and promotes its nuclear translocation and binding to the antioxidant response element (ARE). Exhibits anti-inflammatory properties and increases heme-oxygenase-1 gene expression (~75uM). Also shown to suppress LPS-induced TNF-a secretion in THP-1 monocytes (~ 37.5uM).
Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
