IGF-1 LR3
Lab-made growth-factor peptide
IGF-1 LR3 is an engineered version of IGF-1, the growth factor that growth hormone switches on in the body. It has an extra stretch of building blocks added and one swapped — changes that make it last longer and keep it from being held as tightly by the carrier proteins that normally escort IGF-1 around.
Also known as Long R3 IGF-1 · LR3 IGF-1 · IGF-1 Long Arg3
How it is studied
It lands on the IGF-1 docking spot on cells. Because the changes loosen its grip on those carrier proteins, more of it stays free to reach that docking spot in lab-model systems.
Research context
Studied in cell-biology and laboratory research on IGF-1 signaling, cell growth, and cell multiplication.
Good to know
A powerful growth-factor copy — research use only.
Research area
Growth-hormone & growth-factor (IGF) research. This group of research compounds is studied for how the body's growth-hormone system works. Growth hormone is a natural substance made by a small gland at the base of the brain. Some of these compounds copy the body's own signal that tells that gland to release growth hormone. Others are lab-made copies of growth hormone itself, or of a related messenger the body makes afterward. All are for laboratory research only.
