  • Description
    Neuropeptide B-29 is found in bovine (Bos taurus) and is a novel peptidic ligand for GPR7, identified as a brominated peptide with potent inhibitory activity on cAMP production in CHO cells expressing GPR7.
    Neuropeptide B-29 is widely distributed in various tissues in rats, with mRNA detected in the central nervous system, uterus, ventromedial hypothalamic nucleus, lateral hypothalamic area, and hippocampus, suggesting involvement in feeding regulation, neuroendocrine system, memory, and learning.

  • About TFA salt

    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.
