NF-κB Inhibitor (trifluoroacetate salt)
(Synonyms: SN50 Peptide) 目录号 : GC48985A cell-permeable peptide that blocks nuclear import of NF-κB
Sample solution is provided at 25 µL, 10mM.
NF-κB inhibitor is a synthetic peptide corresponding to the nuclear localization sequence of NF-κB p105 subunit (also known as p50) appended to a hydrophobic sequence to facilitate import into living cells.1 It blocks the nuclear import of p105 in cells treated with activators of NF-κB signaling, including LPS and TNF-α.1 In this way, NF-κB inhibitor blocks gene expression that is regulated by NF-κB.2,3 This peptide is commonly used to evaluate the role of NF-κB signaling in cellular responses.4,5

DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
