RVG29 (YTIWMPENPRPGTPCDIFTNSRGKRASNG), a rabies virus glycoprotein (RVG)-derived peptide containing 29 amino acids, is the most representative ligand peptide for nAchR. RVG29 modification enables nanoparticles to efficiently cross the BBB and recognize neurons, applying to various CNS disorders, such as major depressive disorder (MDD), Alzheimer’s disease (AD), Huntington’s disease (HD), and cerebral ischemia (CI).
Since the RVG29 targets the GABA receptor, using genetic engineering, dendritic cells (DCs) have been engineered to secrete exosomes expressing Lamp2, an exosomal membrane protein, fused with the neuron-specific RVG peptide. The RVG peptide-guided exosomes have the potential in cancer therapy.

Normally, this peptide will be delivered in lyophilized form and should be stored in a freezer at or below -20 °C. For more details, please refer to the manual: Handling and Storage of Synthetic Peptides

Trifluoroacetic acid (TFA) has a significant impact on peptides due to its role in the peptide synthesis process.

TFA is essential for the protonation of peptides that lack basic amino acids such as Arginine (Arg), Histidine (His), and Lysine (Lys), or ones that have blocked N-termini. As a result, peptides often contain TFA salts in the final product.

TFA residues, when present in custom peptides, can cause unpredictable fluctuations in experimental data. At a nanomolar (nM) level, TFA can influence cell experiments, hindering cell growth at low concentrations (as low as 10 nM) and promoting it at higher doses (0.5–7.0 mM). It can also serve as an allosteric regulator on the GlyR of glycine receptors, thereby increasing receptor activity at lower glycine concentrations.

In an in vivo setting, TFA can trifluoroacetylate amino groups in proteins and phospholipids, inducing potentially unwanted antibody responses. Moreover, TFA can impact structure studies as it affects spectrum absorption.
