Sequence and names

Sequence: 83 residues, single chain: a 13-residue N-terminal extension (Met plus porcine GH 1-11 plus Val-Asn) on human IGF-1 with Arg in place of Glu3; three disulfides (19-61, 31-74, 60-65)

Other names: Long R3 IGF-I, Long-(Arg3) insulin-like growth factor-I

The 7.6 kDa figure on some vendor sheets is native IGF-1, not LR3.

Every level includes purity, quantity, identity and a solubility check. Pick the level that matches what you need to know.

$250

Purity and quantity by reversed-phase HPLC with the detector matched to the compound, identity against a reference standard, solubility check. 1 vial.

$550

Silver plus endotoxin (USP 85) and sterility (USP 71). 3 vials.

$700
