Product Detail

1. Product Introduction

IGF-DES, also known as Des(1-3)IGF-1, model IGD, CAS No.112603-35-7, is a truncated synthetic polypeptide analog of insulin-like growth factor 1. This peptide consists of 67 amino acid residues, lacking the first three amino acids at the N-terminus of natural IGF-1. It is prepared by mature peptide synthesis and chromatographic purification technology, followed by freeze-drying treatment and systematic batch quality inspection. It belongs to research-grade biochemical raw material, dedicated to closed in-vitro laboratory research in biochemistry, cell biology and signal transduction mechanism research.

All supplies of IGD are strictly limited to laboratory in-vitro research only. This product cannot be used for human injection, oral administration, clinical trial research, pharmaceutical preparation production, cosmetics manufacturing, food processing and any other application related to human body.

2. Product Characteristics

IGF-DES synthetic polypeptide adopts standardized synthesis and multi-stage purification process. Strict impurity control is implemented in the whole production flow to reduce miscellaneous peptide impurities and guarantee product purity. The finished product exists as white to off-white lyophilized powder, uniform particle condition, with excellent solubility in conventional laboratory aqueous buffer solutions.

Due to N-terminal amino acid truncation modification, this peptide shows weakened binding capacity with IGF binding proteins, and presents unique biochemical characteristics compared with full-length IGF-1. Under specified sealed low-temperature storage conditions, the product has low moisture absorption rate and stable chemical property. Standardized production ensures excellent batch-to-batch consistency, which can provide stable and repeatable experimental data support for long-term comparative research projects. The peptide can be applied for receptor binding exploration and intracellular signaling mechanism research under conventional biochemical reaction systems.
