MW
4731.4 g/mol
Purity
≥99%
Identity & Nomenclature
GLP3 is a synthetic 39-amino-acid peptide reference compound. CAS registry number: 2381089-83-2. Used in in-vitro receptor binding studies and analytical method development.
Molecular Formula & Mass
Molecular formula: C221H343N51O64. Average molecular weight: 4731.4 g/mol. Contains a single isoleucine spacer and multiple α-amino-isobutyric acid (Aib) residues that stabilize α-helical secondary structure in solution.
Purity Specification
Lot release at ≥99% by reversed-phase HPLC. Identity by ESI-MS against the calculated [M+H]+. Net peptide content corrected for residual acetate counterion via AAA.
Physical Form
Lyophilized white powder. Hygroscopic. Reconstitutable in bacteriostatic water; for solubility >5 mg/mL, mild basification (0.1% NaOH then neutralization) improves dissolution kinetics.
Storage
Sealed lyophilized: −20 °C protected from light. Once reconstituted: −80 °C, aliquoted to avoid freeze-thaw. Acetate buffer below pH 5 accelerates hydrolysis.
Certificate of Analysis
Each batch shipped with a COA: HPLC chromatogram, mass spectrum, appearance, peptide content (HPLC + AAA), and counterion identity.
