Alarin is derived from a splice variant of galanin-like peptide (GALP) RNA. It shows potent and dose-dependent vasoconstrictor and anti-edema activity in the cutaneous microvasculature, as was also observed with other members of the galanin peptide family. Since alarin only shares five amino acids with GALP it is unlikely that the peptide can activate GALP-specific receptors. Originally discovered as neuropeptide in 2006 (Santic R et al 2006). It was termed alarin because of the N-terminal alanine and the C-terminal serine. In 2013, this peptide was demonstrated to have antimicrobial activity as well. Active against Gram-negative E. coli ML-35. Deletion of the conserved N-terminal sequence (APAHR) reduced its antimicrobial activity, suggesting that APAHR is essential for its antimicrobial activity. Electron microscopy showed that alarin caused bacterial membrane blebbing. Updated 11/26/2013. Alarin has Antibacterial activity. Alarin was found in brain, Homo sapiens.

About TFA salt: | Trifluoroacetic acid (TFA) is a strong acid, which is commonly used to cleave synthesized peptides from solid-phase resins and is also used to improve HPLC performance in the peptide purification step. By default, custom peptides are delivered as lyophilized TFA salts, and can contain as much as 10-45% TFA. TFA in custom peptides can cause inexplicable discrepancies in subsequent assay data. For instance, TFA in nM concentrations has been shown to interfere with cellular assays, inhibiting cellular proliferation in some instances, and increasing cell viability in others. It has also been found to be an unintended allosteric modulator of the glycine receptor, GlyR. TFA Removal Service is recommended for: > Peptides that will be used in cellular assays > Peptides that will be used as APIs or in manufactured products > For hydrophilic peptides containing numerous basic residues |
