IGF-1 LR3 Pre-Mixed Pen 1mg

Direct Anti Peptide offers the IGF-1 LR3 Pre-Mixed Pen, a precision-engineered research delivery system supplied at ≥98% purity and formulated for exclusive use in controlled laboratory environments. This kit combines a pre-mixed peptide cartridge with a reusable ergonomic pen, sterile needle tips, and a durable carry case — providing researchers with a streamlined, ready-to-use solution. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

The IGF-1 LR3 Pre-Mixed Pen from Direct Anti Peptide represents a significant step forward in research-grade peptide delivery convenience. IGF-1 LR3 — formally known as Insulin-like Growth Factor-1 Long R3 — is a synthetic, lab-engineered analogue of the naturally occurring IGF-1 hormone. Comprising 83 amino acids, this modified peptide variant is widely studied in academic and pharmaceutical research settings for its structural relationship to endogenous growth signalling pathways. The pre-mixed pen format eliminates manual preparation steps, reduces handling errors, and delivers consistent, reproducible results across research protocols. Available exclusively through Direct Anti Peptide, this product is ideal for researchers seeking best price, reliable quality, and fast order fulfilment.

Peptide Structure & Amino Acid Sequence

IGF-1 LR3 is an 83-amino acid synthetic peptide derived from the native IGF-1 sequence, with a key modification at position 3 where glutamic acid is substituted with arginine (R3), and an additional 13-amino acid N-terminal extension. This structural modification significantly reduces binding affinity to IGF-binding proteins (IGFBPs), resulting in a longer circulatory half-life compared to standard IGF-1 in ex vivo models. These properties make IGF-1 LR3 a frequently selected compound in cell biology, receptor binding assays, and growth factor research studies.

• Molecular Classification: Synthetic polypeptide hormone analogue
• Appearance: White to off-white lyophilised powder (pre-mixed in cartridge with bacteriostatic water)
• Solubility: Soluble in aqueous buffered solutions under laboratory conditions
• Purity: ≥98% by HPLC analysis

Purity & Analytical Verification (HPLC & MS)

Every batch of IGF-1 LR3 supplied by Direct Anti Peptide undergoes rigorous analytical testing to confirm identity, purity, and structural integrity. High-Performance Liquid Chromatography (HPLC) is used to verify that purity meets or exceeds the ≥98% threshold, while Mass Spectrometry (MS) confirms the correct molecular mass and sequence fidelity. Certificates of Analysis (CoA) are available upon request, ensuring full traceability and transparency for research documentation and institutional compliance requirements.

Quality Control & Lyophilization Integrity

Prior to pre-mixing, the IGF-1 LR3 peptide is produced via solid-phase peptide synthesis (SPPS) and lyophilised under controlled freeze-drying conditions. Lyophilisation preserves structural integrity, prevents degradation, and extends shelf stability. Each cartridge is pre-mixed with pharmaceutical-grade bacteriostatic water under sterile manufacturing conditions, ensuring consistent concentration and minimising contamination risk across all research applications.

Safety, Handling & Laboratory Precautions

This product is strictly intended for in vitro laboratory research by trained scientific professionals. Researchers must adhere to all applicable institutional biosafety protocols when handling research-grade peptides. Use appropriate personal protective equipment (PPE), including gloves and eye protection. Avoid direct contact with skin or mucous membranes. This compound is not evaluated for safety or efficacy in humans or animals and must never be used outside of a regulated research environment.

Reconstitution, Packaging & Storage

The IGF-1 LR3 Pre-Mixed Pen kit includes the following components:

• 1 x Pre-Mixed Cartridge — peptide combined with bacteriostatic water, ready for immediate research use
• 1 x Reusable Ergonomic Peptide Pen — precision-dosing delivery device
• 1 x Protective Carry Case — durable, organised storage solution
• 3 x Sterile Needle Tips — single-use, safety-compliant

Store cartridges at 2–8°C when not in use. Protect from light and moisture. Do not freeze pre-mixed cartridges. Once prepared, use within the timeframe recommended for bacteriostatic water-reconstituted peptides under standard laboratory storage conditions.

Intended Research Use & Market Positioning

IGF-1 LR3 is a widely referenced peptide in academic and pharmaceutical research, particularly in studies examining growth factor receptor interactions, cellular proliferation assays, and anabolic signalling pathway investigations. The pre-mixed pen format is specifically designed to support high-throughput research workflows, offering reproducibility and convenience that loose lyophilised formats cannot match. Direct Anti Peptide positions this product as a premium, compliance-ready research tool for professional laboratory environments.
