What is GLP-3 R?

GLP-3 R is a 39 amino acid synthetic peptide studied as a triple agonist of the GLP-1, GIP and glucagon receptors. Its listing describes Aib at positions 2 and 13, a C20 fatty diacid side chain on lysine 20 and a C terminal amide. It is studied in metabolic research. It is supplied as a lyophilized powder for in vitro and preclinical laboratory research only.

Full specifications

Sequence: 39-residue GLP-1R / GIPR / GCGR triple agonist; Aib at positions 2 and 13; γGlu-2×OEG-C20 diacid acylation at Lys20; C-terminal amide
Length: 39 amino acids
CAS number: 2381089-83-2
Molecular formula: C221H342N46O68
Molecular weight: 4731.4 g/mol
Form: Lyophilized powder in a glass vial
Purity standard: 98% or higher (brand listing)
Storage: Minus 20 °C long term. 2 to 8 °C once reconstituted, use within 30 days.

How GLP-3 R is tested

A good GLP-3 R listing comes with a lab report for the exact lot in the vial. These are the results to look for:

Purity (HPLC)
How much of the sample is the compound
Identity (MS or LCMS)
Confirms it is the right molecule
Net content
The real mg in the vial versus the label
Endotoxin (LAL)
Bacterial residue, reported in EU
Sterility
Confirms nothing is growing in the vial
Heavy metals (ICP-MS)
Arsenic, cadmium, lead and mercury

Storage and handling

Lyophilized GLP-3 R is stable at room temperature while it ships. For long term storage keep vials at minus 20 °C. Once reconstituted for laboratory use, store at 2 to 8 °C and use within 30 days.

GLP-3 R vs GLP-2 T and GLP-1 S

GLP-3 R targets three receptors (GLP-1, GIP and glucagon). GLP-2 T targets two (GLP-1 and GIP). GLP-1 S targets one (GLP-1).
