IGF-1 LR3: Research Background
Mechanism of Action: IGF-1 LR3 is a recombinant IGF-1 analog with reduced IGFBP affinity, producing a half-life ~20–30x longer than native IGF-1. Enables sustained IGF-1 receptor activation for body composition, myocyte proliferation, and anabolic signalling research.
Research Applications: IGF-1 receptor biology, muscle cell proliferation and differentiation, anabolic signalling pathways, comparison with native IGF-1.
Storage & Reconstitution
Storage: Store lyophilized peptide at -20°C. Reconstituted: 4°C, use within 28 days.
Reconstitution Protocol: Add bacteriostatic water or 10mM acetic acid per protocol. Swirl gently.
Quality Verification
Every QSC IGF-1 LR3 batch undergoes: HPLC purity analysis (≥99% specification) · Mass spectrometry molecular verification · Impurity profiling · Batch traceability to published COA.
Certificates of Analysis are published on the product page and independently verifiable via the Janoshik testing portal.
