Buy Pharmaqo US IGF-DES 1-3 UK | Truncated IGF-1 Analog for Research

Pharmaqo US – IGF-DES 1-3 – Available Now in the UK

For researchers and scientists investigating muscle physiology, cellular hypertrophy, and tissue regeneration, Pharmaqo US – IGF-DES 1-3 delivers a premium research-grade truncated analog of Insulin-like Growth Factor-1. IGF-1 DES (Des(1-3)IGF-1) is a naturally occurring variant of human IGF-1, first isolated from bovine colostrum, human brain, and porcine uterus, characterized by the absence of the N-terminal tripeptide Gly-Pro-Glu . This truncation, specifically the lack of the glutamate residue at position 3, results in dramatically reduced binding to IGF-binding proteins (IGFBPs) while retaining full affinity for the IGF-1 receptor, making it approximately 10-fold more potent than regular IGF-1 in stimulating cellular proliferation and hypertrophy in vitro . Now available from uksteroidshop.co.uk, your trusted UK-based supplier, you can access this premium research compound with the assurance of Pharmaqo US quality.

Whether you’re conducting muscle biology research in Birmingham, studying growth factor signaling in Manchester, or investigating tissue repair mechanisms in Glasgow or Edinburgh, we deliver nationwide. Research facilities across London, Leeds, Liverpool, Bristol, Nottingham, Sheffield, Cardiff, and Belfast trust us for their advanced peptide needs. Experience the quality and consistency required for serious scientific investigation.

Why Choose uksteroidshop.co.uk for Pharmaqo US IGF-DES 1-3

Premium Research-Grade Quality

Pharmaqo US is renowned for producing high-quality research-grade peptides. Every batch of Pharmaqo US – IGF-DES 1-3 meets stringent quality benchmarks, with purity exceeding 97% by SDS-PAGE and HPLC analysis . Endotoxin levels are maintained at less than 50 EU/mg as determined by LAL method, ensuring suitability for sensitive research applications . When you purchase Pharmaqo US IGF-DES from us, you’re investing in premium quality for your laboratory work.

Superior Biological Potency

IGF-1 DES exhibits approximately 10-fold greater potency than full-length IGF-1 in stimulating cell proliferation and hypertrophy . This enhanced activity results from the absence of the glutamate residue at position 3, which drastically reduces binding to IGF-binding proteins while maintaining full receptor affinity . The ED50 as determined by cell proliferation assays using serum-free human MCF-7 cells is less than 2 ng/ml, corresponding to a specific activity of >5.0 × 10⁵ IU/mg .

Distinctive Pharmacokinetic Profile

The N-terminal truncation of IGF-1 DES leads to unique pharmacokinetic properties that distinguish it from the full-length molecule:

  • Shorter Half-Life: The half-life of des(1-3)IGF-I in rats is approximately 20.5 minutes, compared to 228.3 minutes for intact IGF-I

  • Rapid Clearance: The truncated variant is cleared much more rapidly from circulation, with greater urinary excretion

  • Tissue Distribution: Preferential uptake is observed in skeletal muscle, kidney, and testis

Key Research Findings on IGF-1 DES

Structural Characteristics

IGF-1 DES is a truncated variant of human IGF-1 lacking the N-terminal tripeptide Gly-Pro-Glu . This post-translational cleavage product has been isolated from multiple biological sources including bovine colostrum, human brain, and porcine uterus . The absence of the glutamate residue at position 3 is responsible for its dramatically reduced binding to IGF-binding proteins .

Enhanced Receptor Activation

Systematic studies have shown that removal of Glu3 accounts for the dramatic loss of binding affinity for IGF-BPs, while the variant retains affinity of intact IGF-I for the signaling IGF-type I receptor . Des-(1–3)-IGF-I has an average of only ∼1% of the affinity of native IGF-I for the IGF-BPs . This reduced binding to carrier proteins increases the concentration of free, bioavailable hormone available to interact with cellular receptors.

Cellular Effects

IGF-1 DES binds the IGF-1 receptor (a cell-surface tyrosine-kinase receptor) more readily than full-length IGF-1, triggering intracellular signaling that promotes cell growth and survival . It accelerates receptor-mediated activation of the PI3K/Akt pathway, a signaling cascade involved in protein synthesis . In plain terms, it more effectively “turns on” growth and repair signals in target cells.

Blood-Brain Barrier Interactions

Research demonstrates that des(1-3)IGF-1 has a shorter half-life in blood, slower influx rate into brain, and no alteration in pharmacokinetics after addition of nonradiolabeled peptide, in contrast to full-length IGF-1 which exhibits saturable transport . This suggests distinct CNS delivery mechanisms for the truncated variant.

Tissue Distribution Patterns

Following intravenous administration in rats, maximal accumulation of all IGF peptides was found in the kidney . Skeletal muscle, kidney, and testis showed preferential uptake of the truncated variants . The distribution pattern for IGF-I and -II was: kidney > pancreas > small intestine > liver > duodenum > stomach > lung > spleen > heart > large intestine > testis > brain > skeletal muscle .

How to Use Pharmaqo US IGF-DES 1-3 for Research Applications

For research professionals utilizing Pharmaqo US – IGF-DES 1-3 in laboratory settings, understanding proper protocols is essential for experimental validity.

  • Form & Potency: This product is supplied as a lyophilized (freeze-dried) powder in a sterile vial containing Pharmaqo US IGF-DES 1-3. (Specific vial potency would typically be listed on product packaging.)

  • Reconstitution: IGF-1 DES must be reconstituted with sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL .

    • Briefly centrifuge the vial prior to opening to bring contents to the bottom

    • Gently swirl (do not vortex) to dissolve; avoid vigorous shaking

    • Stock solutions should be apportioned into working aliquots and stored at ≤-20°C

    • Further dilutions should be made in appropriate buffered solutions

  • Half-Life Considerations: Research studies demonstrate that des(1-3)IGF-I has a half-life of approximately 20.5 minutes in rats, substantially shorter than the 228.3 minutes of intact IGF-I . This rapid clearance should be considered when designing experimental protocols.

  • Administration Routes for Research:

    • Intravenous (IV): Used in pharmacokinetic studies to determine half-life and tissue distribution

    • Subcutaneous (SC): Human studies have used 20–50 µg/kg administered subcutaneously once or twice daily for up to two weeks

    • Intramuscular (IM): For localized tissue studies, direct intramuscular injection may be appropriate

  • Storage:

    • Lyophilized powder: 12 months from date of receipt, -20 to -70°C as supplied

    • After reconstitution: 1 month at 2-8°C under sterile conditions; 3 months at -20 to -70°C under sterile conditions

    • Avoid repeated freeze-thaw cycles; aliquot into working volumes

  • In Vitro Applications: Cell culture studies have utilized concentrations established through dose-response curves. The ED50 for MCF-7 cell proliferation is less than 2 ng/ml .

  • In Vivo Applications: Animal studies have demonstrated enhanced potency of des(1-3)IGF-I relative to IGF-I in growth hormone-deficient animals, with selective anabolic effects particularly evident in gut tissues .

  • Important Research Considerations:

    • For research use only; not for human consumption

    • Not approved for therapeutic use by FDA, EMA, or other regulatory authorities

    • Must be used under approved research protocols with appropriate oversight

    • Monitor blood glucose in relevant animal models due to insulin-like activity
