Every report

Every figure below is transcribed from the laboratory's own document, and every card shows how to pull up the original with that laboratory. Two kinds of report appear here: a lot verification, which tests the very lot printed on the vial, and a reference report, an outside test of the batch the manufacturer made.

Overview

PT-141.

PT-141 is a ring. A lactam bridge between the side chains of aspartic acid and lysine closes its seven residues, and two of those residues, N-acetyl norleucine and D-phenylalanine, fall outside the standard set. Cyclizing a peptide this way fixes it in a single shape, which is why such rings are built.

It is an analog of alpha-melanocyte-stimulating hormone, developed by Palatin Technologies; PT stands for the company. Many of our peptides finish with an amide, but this one ends in a free carboxylic acid, and the analytical record confirms it. Supplied as 10 mg, freeze-dried.

PuraCore offers no advice on how any material is used, prepared or applied. Deciding whether it fits your research rests with you or your institution.
