    INTRODUCE

    This catalog introduces available research-grade peptides and related bioactive molecules, covering research fields including skin and tissue repair, anti-inflammation, metabolic regulation, mitochondrial function and antioxidation.

    These products are synthesized via Solid-Phase Peptide Synthesis (SPPS) technology, purified by High Performance Liquid Chromatography (HPLC) and characterized by Mass Spectrometry (MS).

    They are supplied as high-purity lyophilized powder. A Certificate of Analysis (COA) is provided for each batch, with full batch traceability.

    1.Specifications & Storage

    Our research peptides are available in multiple packaging specifications ranging from milligram to gram scale, to meet diverse laboratory research demands.
    For long-term preservation, store lyophilized peptides at -20°C under dry and dark conditions. Avoid repeated freeze-thaw cycles to prevent peptide degradation after reconstitution.

    2.Custom Peptide Synthesis Service

    We offer custom peptide synthesis services, including sequence design, peptide modification such as acetylation, amidation, fluorescent labeling and biotin labeling.

    Custom products can be produced according to your requested purity level and quantity, suitable for custom cell assays and preclinical animal studies.

    3.Sample & Delivery

    Small quantity samples are available for preliminary lab validation.
    Standard lead time varies based on peptide length and modification complexity. We use cold-chain packaging for sensitive peptide products to guarantee quality during transit.

    4.Quality Control
    Each batch undergoes strict quality control tests including HPLC purity detection, MS molecular weight verification, water content and residual solvent test.
    All testing records are archived, enabling complete batch traceability for your research documentation.

    ECHEMI Editorial Reference
    Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1). It differs from native IGF-1 in that it possesses an arginine instead of a glutamic acid at the third position in its amino acid sequence ("arginine 3"), and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN) ("long"), for a total of 83 amino acids (relative to the 70 of IGF-1).
