Merck, 481480-500UG, NF-κB SN50, Cell-Permeable Inhibitor Peptide

General description
Contains the nuclear localization sequence (NLS) of the transcription factor NF-κB p50 linked to the hydrophobic region (h-region) of the signal peptide of Kaposi fibroblast growth factor (K-FGF). The N-terminal K-FGF h-region confers cell-permeability, while the NLS (360-369) inhibits translocation of the NF-κB active complex into the nucleus. In murine endothelial LE-II cells induced by LPS, NF-κB nuclear translocation is maximally inhibited at 18 µM.
NF-κB SN50, CAS 213546-43-3, is a cell-permeable peptide that contains the NLS sequence of NF-κB p50 linked to the hydrophobic region of K-FGF. Inhibits translocation of the NF-κB into the nucleus.
