what each one is
Bacteriostatic Water
Sterile preserved laboratory diluent
Bacteriostatic water is not a peptide but a laboratory reagent: sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. The benzyl alcohol inhibits the growth of common contaminating organisms, which allows a sealed vial to be accessed more than once over the course of a study without the reagent itself becoming a source of microbial contamination.

Recombinant IGF-1 analog polypeptide
IGF-1 LR3 is Long R3 insulin-like growth factor 1, a recombinant analog of human IGF-1 carrying an arginine substitution at position 3 and a 13-residue N-terminal extension. Those two modifications are what define it: they substantially reduce its affinity for the insulin-like growth factor binding proteins (IGFBPs) that sequester native IGF-1 in culture systems.

What is bacteriostatic water?
It is sterile water containing 0.9% benzyl alcohol as a bacteriostatic preservative. Verve supplies it as a laboratory reagent for research use only, not for human or veterinary use.
What is it used for in research?
It is used as a diluent for reconstituting lyophilized research compounds and for preparing working dilutions from stock solutions in a laboratory setting.
What is IGF-1 LR3?
IGF-1 LR3 is Long R3 insulin-like growth factor 1, a recombinant analog of human IGF-1 with an arginine substitution at position 3 and an N-terminal extension. Verve supplies it as a research compound for laboratory use only, not for human or veterinary use.
How does IGF-1 LR3 differ from native IGF-1?
Its structural modifications reduce affinity for IGF binding proteins, so more of the ligand remains unbound in culture systems. Researchers use that property to control free-ligand availability in in-vitro models.
