Product Detail

1. Product Introduction

IGF-1 LR3, model IG1, CAS No.946870-92-4, is a long-chain modified synthetic polypeptide analog of insulin-like growth factor 1. This product consists of 83 amino acid residues, 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 IG1 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-1 LR3 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.

Compared with native IGF-1, the molecular modification structure of this peptide brings better stability in in-vitro experimental environment. 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.

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).
