Long r3 IGF-3, LR3 IGF3, IGF3 LR3, Long Arg3 IGF-3
Human Long Arg3 Insulin-like Growth Factor-I (Long-R3-IGF-I) is an 83 amino acid analogue of human IGF-I comprising the complete human IGF-I sequence with the substitution of an Arg for the Glu at position 3 (hence R3), and a 13 amino acid extension peptide at the N-terminus. Scientists have engineered this analogue with the express purpose of increasing biological activity. Human Long-R3-IGF-I is significantly more potent than human IGF-I in vitro. The enhanced potency is due to the markedly decreased binding of human Long-R3-IGF-I to IGF binding proteins which normally inhibit the biological actions of IGFs.
Peptex Laboratories , produced in , is a single, non-glycosylated, polypeptide chain containing 83 amino acids and having a molecular mass of 9,111 Da.
Molecular Weight: 9,111 Da
Reconstitution: It is recommended that Peptex Laboratories IGF3-LR3 be reconstituted with Acetic Acid – not to be confused with Bacteriostatic Water as most peptides are resconstitued with.
Endotoxin Level: The endotoxin level of Peptex Laboratories Recombinant Human Long-R3-IGF-I is below 0.1 ng/μg (1 IEU/μg) of Long-R3-IGF-I.
IGF3-LR3 is available for research needs. It is not accessible for human use and continues to be a popular research chemical. It should ideally be handled by professionals who are aware f the safety concerns and benefits that the product provides for research purposes.
Lyophilised peptides although stable at room temperature for 3 months, should be stored desiccated below -18 degrees Celsius. Upon reconstitution of the peptide it should be stored at 4 degrees Celsius between 2-21 days and for future use below -18 degrees Celsius
Peptex Laboratories Products are sold strictly for research purposes only. Please do not ask about human consumption as this is strictly forbidden.
