Semaglutide

Description

Semaglutide is a synthetic, chemically modified peptide research material derived from the GLP-1 peptide sequence and produced through controlled peptide synthesis and conjugation processes. Its structure incorporates defined amino-acid substitutions and a covalently attached lipid-derived side chain, making it suitable for analytical, biochemical, and molecular research involving modified peptide systems. The material is commonly supplied in lyophilized form to support stability and integrity during appropriate laboratory storage and handling.

Research Applications:

Semaglutide may be utilized in controlled laboratory research settings for applications such as:

• Analytical characterization of modified peptide structure, identity, and physicochemical properties
• Investigation of peptide-receptor interactions in controlled biochemical and cell-based assay systems
• Evaluation of structural stability, degradation, and molecular behavior under defined experimental conditions
• Examination of structure-activity relationships associated with amino-acid substitutions and lipid-conjugated peptide designs

Storage and Handling:

• Store lyophilized material at -20°C or according to batch-specific supplier documentation.
• Protect the material from excessive moisture, heat, and prolonged light exposure.
• Once prepared in solution, follow validated stability data and the specific laboratory protocol for storage conditions.
• Avoid unnecessary repeated freeze-thaw cycles and use appropriate laboratory handling procedures to minimize contamination and degradation.

Product Specifications:

• Purity: Refer to batch-specific HPLC results or Certificate of Analysis
• Appearance: Typically supplied as a white to off-white lyophilized powder; confirm against batch-specific documentation
• Solubility: Dependent on formulation, concentration, pH, and solvent system; refer to supplier-specific technical documentation

Compliance Notice:

Semaglutide is FOR RESEARCH USE ONLY. It is not intended for human or veterinary use. This product is supplied exclusively for controlled laboratory, analytical, and in vitro research purposes and is not intended for diagnostic, therapeutic, or clinical applications.

Technical Note: The molecular formula C₁₈₇H₂₉₁N₄₅O₅₉ and molecular weight of approximately 4113.58 g/mol correspond to the commonly referenced semaglutide molecular structure. Semaglutide is not simply an unmodified peptide sequence; it contains specific amino-acid substitutions, including Aib at the position corresponding to residue 8 of GLP-1, an Arg substitution at the position corresponding to residue 34, and a lipid-derived side-chain modification attached to the Lys residue corresponding to position 26. Always check final product-page specifications against the supplier documentation and batch-specific Certificate of Analysis (COA), especially where formulation, counterions, hydration state, or analytical reporting conventions may affect reported values.
