About This Material

IGF-LR3

Laboratory research material

IGF-LR3 (Insulin-like Growth Factor 1, Long Arg3) is a synthetic IGF-1 analogue carrying a 13-residue N-terminal extension and an arginine swap at position 3. Together these changes sharply lower affinity for IGF-binding proteins, lengthening functional half-life and improving receptor availability — making it a workhorse in proliferation and anabolic-signalling research.

Lyophilised powder, 1mg vial, ≥99% purity by HPLC, Certificate of Analysis on request. Dispatched from the UK, for research use only.

Research applications

  • Cellular proliferation and myoblast differentiation studies
  • IGF-1 receptor binding and PI3K/Akt downstream signalling
  • Glucose uptake and insulin-sensitivity pathway research
  • Muscle protein synthesis and anti-catabolic mechanism work
  • mTOR activation and comparisons against native IGF-1

Specifications

  • Form: Lyophilised powder
  • Purity: ≥99% (HPLC verified)
  • Storage: −20°C, protected from light and moisture
  • Available sizes: 1mg
  • Certificate of Analysis: available on request
