IGF-1 LR3

Long Arg3 insulin-like growth factor 1 analogue. Isolated for its structural simplicity and synthetic accessibility, IGF-1 LR3 is produced as a lyophilised solid and sealed under inert atmosphere.

Every batch moves through the full Six-Step protocol — solid-phase Fmoc synthesis, TFA cleavage, reverse-phase HPLC purification, and ESI-TOF mass-spec confirmation. The lot shipped carries ≥ 99% HPLC-MS purity with residual solvent and endotoxin assays signed by an independent laboratory.

Lyophilised vials are stable at −20 °C in their sealed amber container. In bacteriostatic water, HPLC-verified purity holds for approximately four weeks under refrigeration; single-thaw only.
