In the evolving field of molecular biology, the study of transcription factor regulation has become a cornerstone for la NF-κB SN50M, Cell-Permeable Inactive Control Peptide boratory investigations. Among the specialized tools available to researchers, the SN50 peptide stands out as a unique instrument designed for high-precision studies. As someone who follows the latest developments in synthetic biology and peptide research, I have found the technical profile of this molecule to be particularly fascinating for those exploring cellular signaling pathways.
Defining the SN50 Peptide Entity
At its core, the SN50 peptide is a specialized synthetic construct. It is classified as an NF-κB cell-permeable inhibitory An inactive control for SN50 peptide (Cat. No. 481480). Corresponds to the SN50 peptide sequence with substitutions of Asn for Lys363 and Gly for Arg364 in peptide (SN50). The molecular architecture of this peptide is ingenious: it combines the hydrophobic region of the signal peptide of Kaposi fibroblast growth factor (K-FGF) with the nuclear localization sequence (NLS) of the NF-κB p50 subunit.
This specific design allows the molecule to function as a cell-permeable nuclear factor-κB (NF-κB) inhibitory peptide. By acting as a decoy, it prevents the translocation of the NF-κB active complex into the nucleus, which is a critical step in various cellular signaling cascades.

The primary reason researchers utilize the SN50 peptide is its ability to serve as a cell-permeable inhibitor of NF-κB translocation. In experimental settings, this is vital for understanding how specific transcription factors interact with the nuclear pore complex. Because the SN50 is a synthetic peptide, it can be introduced into controlled environments—such as cell cultures (e.g., mouse endothelial LE-II cells)—to observe how the inhibition of nuclear import alters cellular behavior.
It is important to note that SN50 is a NF-κB cell-permeable inhibitory peptide that specifically targets the translocation process. Unlike broad-spectrum inhibitors, this molecule offers a more granular approach to studying the NF-κB pathway. For those looking at control variables, the SN50 peptide is often used alongside the SN50M peptide, which serves May 29, 2024 — Peptide inhibits translocation of the NF-κB active complex into the nucleus.

E-E-A-T and Scientific Integrity
When evaluating research-grade peptides, reliability is paramount. The industry standard for these molecules often requires a purity level of ≥95% or even ≥97% as measured by HPLC (High-Performance Liquid Chromat Your source for peptide research, applications, and scientific guides. ography). Researchers prioritize entities that provide clear documentation, such as the CAS number (213546-43-3), to ensure the consistency of their experimental outcomes.
Whether you are investigating the nuclear factor NF-κB p50 subunit or exploring new ways to modulate protein-protein interactions, the quality of the peptides used determines the validity of the data. Reputable sources often emphasize that these tools are strictly for laboratory research and are not intended for clinical or human use.
Insights into Recent Investigations
The interest in the SN50 peptide continues to grow as we uncover more about its specificity. Recent discussions in the scientific community have highlighted that the effects of this peptide can be both dose-dependent and cell-type-dependent. This nuance is essential for any researcher planning an experiment.
