IGF-1 LR3

IGF-1 LR3, also known as Long R3 IGF-1, is a synthetic analog of insulin-like growth factor-1 intended for controlled laboratory research. Its structure incorporates an arginine substitution at position 3 together with an additional 13-amino-acid N-terminal extension, providing a clearly defined material identity for analytical and non-clinical research workflows.

Vertex Labs supplies IGF-1 LR3 as a 1 mg lyophilized powder in a sealed research vial. The material is intended for qualified laboratory personnel working in controlled environments where accurate identification, batch documentation, storage controls, and consistent research-material handling are required.

Product Specifications

Research Material Identification

IGF-1 LR3 is distinguished from standard IGF-1 by its defined structural modifications, including the position-3 arginine substitution and extended N-terminal sequence. These characteristics, together with batch-specific documentation, support accurate material identification and traceability within controlled laboratory workflows.

Researchers should review the product label and associated batch documentation before incorporating the material into an analytical protocol. Vertex Labs maintains product and quality documentation to support consistent identification across individual research batches.

Quality & Documentation

Each batch released by Vertex Labs is supported by batch-level documentation and Certificate of Analysis availability following quality review. Documentation may include identity confirmation, purity assessment, active weight verification, labeling review, and other analytical information relevant to the specific batch.
