Pinealon liquid spray

What is it for?

Pinealon, the Glu-Asp-Arg tripeptide from the Khavinson bioregulator series, in solution at 1.0 mg/mL — 10 mg across a 10 mL atomiser, a nominal 100 micrograms per actuation. Short peptides of this kind go into solution readily and stay there, which is what makes a ready-made format practical. Refrigerate and protect from light.

• Reading a certificate for a tripeptideShort peptides are easier to synthesise and harder to characterise than long ones. What an HPLC trace can and cannot resolve at three residues, and why mass spectrometry carries more of the weight.
• Why tripeptides behave differently in solutionMost peptide handling advice is written for chains long enough to fold. At three residues there is no structure to lose, which removes some problems and introduces others.
• TFA salt vs acetate salt: which counter-ion your peptide carries and when it mattersAlmost every research peptide arrives as a trifluoroacetate salt, because TFA is used to cleave and purify it. The counter-ion is part of the powder's weight and, for some cell work, part of the result. What the salt form is, how much TFA a given peptide can carry, the evidence that it affects cells, and when to ask for acetate.
