IGF-1 LR3

Description

IGF-1 LR3 is a recombinant polypeptide research material structurally derived from human insulin-like growth factor-I. The molecule includes an extended N-terminal sequence and an amino-acid substitution that differentiates it from native IGF-I. It is produced through controlled recombinant expression and purification and used in laboratory settings for analytical, biochemical, receptor-binding, and molecular investigations under defined experimental conditions. The material is commonly supplied in lyophilized form to support stability and integrity during appropriate laboratory storage and handling.

Research Applications:

IGF-1 LR3 may be utilized in controlled laboratory research settings for applications such as:

• Analytical characterization of recombinant polypeptide identity, molecular size, and structural integrity
• Investigation of IGF-associated receptor interactions in controlled biochemical and cell-based assay systems
• Evaluation of protein stability, degradation, and physicochemical behavior under defined laboratory conditions
• Examination of structure-function relationships involving modified IGF-I analogues in experimental research models

Storage and Handling:

• Store lyophilized material at -20°C or according to the manufacturer’s batch-specific storage instructions.
• Protect the material from excessive moisture, heat, and prolonged light exposure.
• Once prepared in solution, follow validated stability and buffer-specific storage requirements for the exact recombinant preparation.
• Avoid unnecessary repeated freeze-thaw cycles and use appropriate protein-handling procedures to minimize contamination, aggregation, and degradation.

Product Specifications:

• Purity: Refer to batch-specific HPLC, SDS-PAGE, mass spectrometry, or Certificate of Analysis results
• Appearance: Typically supplied as a white to off-white lyophilized material; verify against batch-specific documentation
• Expression System: Supplier-specific; confirm the recombinant host system used for the actual product
• Solubility: Dependent on concentration, pH, formulation, buffer composition, and recombinant construct

Compliance Notice:

IGF-1 LR3 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. Misuse of this product is strictly prohibited and may violate applicable federal, state, or local laws. By purchasing this product, the buyer represents and warrants that it will be used solely for legitimate laboratory research purposes.

Technical Note: IGF-1 LR3 should not be treated as a small synthetic peptide with universally interchangeable chemical specifications. It is a recombinant 83-amino-acid IGF-I analogue containing a 13-residue N-terminal extension and an arginine substitution corresponding to position 3 of IGF-I. Exact molecular formula, amino-acid sequence, terminal configuration, expression system, and analytical characteristics may differ depending on the recombinant construct and supplier. Final product-page specifications should therefore match the manufacturer documentation and the batch-specific Certificate of Analysis (COA).
