In the literature
IGF-1 LR3 is an 83-amino-acid analogue of IGF-1, carrying a 13-residue N-terminal extension and an arginine substitution at position 3, supplied as a lyophilized powder in a sealed vial.
IGF-1 LR3 is studied in cell-culture models as an analogue with reduced affinity for the IGF-binding proteins compared with the 70-residue native sequence.
Questions about IGF-1 LR3
About OXpeptides
Who we are
OX RESEARCH LTD operates OXpeptides. Company number 17464288 (England and Wales). We supply lyophilized research peptides in sealed glass vials, and one laboratory diluent, to researchers and laboratories.
How we work
Each production lot is sent to an independent third-party laboratory for HPLC purity and mass-spectrometry identity confirmation. The certificate is published on the product page with its lot number and its date as soon as the laboratory returns it; a lot still at the laboratory says so, in those words, rather than borrowing the figures of another lot. Every vial is crimp-sealed and carries the compound name, the net quantity in milligrams and the lot number. Orders ship from the warehouse that serves the delivery address, tracked.
Who we sell to
Research use only. Not for human or veterinary use. In practice that means three things we do not do: we publish no quantities, no routes and no schedules anywhere on this site, and support declines those questions; we publish no certificate we do not hold; and we publish no customer review that does not come from a verified order.
