Description
Product Detail

This compound lyophilized laboratory reagent is synthesized via solid-phase synthesis under strict aseptic and controlled manufacturing conditions. Through multi-step synthesis, desalting and vacuum freeze-drying procedures, a stable, fine dry powder is obtained. The finished reagent shows no caking, discoloration, sticky aggregation or visible foreign particulate matter.

Multi-stage reversed-phase chromatographic purification is applied to eliminate truncated fragments, coupling agent residues and salt-based impurities. HPLC testing confirms each synthetic component achieves ≥99% purity, delivering stable, repeatable experimental data for cell-level assays, molecular binding research and laboratory model studies.

Packaged in individual crimp-sealed glass containers, this reagent supports flexible procurement options and multi-container assembled kits, meeting diverse research workflows from preliminary screening experiments to large-batch laboratory validation.

The full manufacturing workflow follows standardized internal quality-control protocols, covering raw material validation, component proportion optimization, impurity removal, desalting and low-temperature sterile lyophilization. Every batch undergoes comprehensive physical and chemical testing prior to shipment. COA certificates, HPLC spectograms, mass-spectrometry identification reports and batch inspection logs are available to support laboratory filing and experimental verification.

Important Research Statement: This product is intended solely for scientific laboratory research. It shall not be used for human-related trials, clinical assessment, medical diagnosis or consumer-grade applications. Any use beyond laboratory research scope is prohibited.

The lyophilized reagent is sensitive to temperature shifts, moisture and air exposure. For long-term storage, keep unopened containers tightly sealed at -20℃ under dry, dark and low-humidity conditions. Avoid repeated freeze-thaw cycles, high-temperature exposure and direct strong light irradiation which may damage molecular structure. Once the seal is opened, prepare working solution promptly to reduce moisture absorption and external contamination risks.

Global logistics support is available for bulk procurement. Custom labeling and packaging can be provided upon request. Each container adopts premium butyl rubber stopper plus aluminum crimp cap to maintain internal anhydrous status. Shock-absorbing inserts, waterproof barrier bags and reinforced cartons are adopted for outer-packaging to lower risks of mechanical damage, powder leakage and moisture deterioration during transit.

Quality Control & Core Advantages

Accurately assembled synthetic peptide components. Mass-spectrometry testing validates molecular integrity, well-suited for molecular-interaction-oriented laboratory research.

Multi-level purification & desalting workflow. Successive chromatographic purification plus desalting treatment effectively removes synthetic by-products, organic residues and excess salt components that interfere with cell and lab model experiments.

Stable batch-to-batch consistency. Fixed synthesis formula, component proportion, purification and lyophilization parameters are enforced for each production batch. Minor fluctuations in appearance, solubility and structural indicators are acceptable for continuous research projects and repeated laboratory testing.

Complete batch test documentation. Each lot supplies HPLC purity report, MS verification and full COA document set, convenient for lab record-keeping and institutional audit checks.

Flexible ordering modes. Bulk multi-container kits are supported to match different experimental consumption demands.

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).
