What it is
IGF-1 LR3 (Long R3 IGF-1) is a recombinant analogue of human insulin-like growth factor 1. It has arginine in place of glutamate at position 3 and a 13-amino-acid extension at the N-terminus, 83 amino acids in all.
Identity
| Type | Recombinant protein, 83 amino acids |
|---|---|
| Molecular weight | About 9.1 kDa |
What the published research covers
The changes greatly reduce binding to the IGF-binding proteins, so more of it stays free in solution. It is widely used as a growth supplement in mammalian cell culture.
Regulatory status
Not approved by the FDA for any use. Supplied for laboratory research only.
Testing and documentation
A protein of this size is characterized by mass spectrometry and HPLC or gel electrophoresis. The certificate of analysis for the batch is reachable from the code on the vial.
