— Product Overview
Description
GLP-2 TZ, also written GLP-2TZ, is a 39-residue synthetic peptide that ends in a C-terminal amide. One of its two lysines is acylated with a fatty-acid chain joined by a short linker, so it weighs much more than an unmodified 39-residue chain would.
The GLP-2 TZ peptide comes in three sizes, 10mg, 20mg and 60mg, each as freeze-dried (lyophilized) powder in a sealed vial.
Store vials out of light. A reconstituted solution that must be frozen should be split into aliquots first, so it is not thawed and refrozen again and again.
For research use only. Not for use in humans or animals. Each GLP-2 TZ batch is tested by an independent third-party lab; its lab report (COA) is posted on our COAs page.
