IGF-1 LR3 1mg – 100 Vials Bulk Pack (50% Off)

Product Overview

Revo Peptide is proud to offer IGF-1 LR3 (Insulin-like Growth Factor-1 Long R3) in a premium bulk configuration of 100 vials at 1mg per vial — now available at 50% off the standard per-unit price. This bulk pack is designed specifically for research institutions, academic laboratories, and professional peptide researchers requiring consistent, high-volume supply of a well-characterized, analytically verified research peptide. IGF-1 LR3 is a synthetic, extended-chain analogue of endogenous IGF-1, engineered with an 83-amino acid sequence that includes a 13-amino acid N-terminal extension and a substitution of Arg for Glu at position 3, resulting in significantly reduced binding affinity to IGF-binding proteins. This structural modification makes it a highly valuable tool in cellular and molecular biology research contexts. Buy online today and take advantage of our best bulk pricing available.

Peptide Structure & Amino Acid Sequence

IGF-1 LR3 features a fully characterized 83-residue sequence: H-Met-Phe-Pro-Ala-Met-Pro-Leu-Ser-Ser-Leu-Phe-Val-Asn-Gly-Pro-Arg-Thr-Leu-Cys-Gly-Ala-Glu-Leu-Val-Asp-Ala-Leu-Gln-Phe-Val-Cys-Gly-Asp-Arg-Gly-Phe-Tyr-Phe-Asn-Lys-Pro-Thr-Gly-Tyr-Gly-Ser-Ser-Ser-Arg-Arg-Ala-Pro-Gln-Thr-Gly-Ile-Val-Asp-Glu-Cys-Cys-Phe-Arg-Ser-Cys-Asp-Leu-Arg-Arg-Leu-Glu-Met-Tyr-Cys-Ala-Pro-Leu-Lys-Pro-Ala-Lys-Ser-Ala-OH. The N-terminal Met-containing extension and the Arg3 substitution collectively distinguish LR3 from native IGF-1, conferring unique binding and stability properties that are of significant scientific interest. Each vial in this bulk pack contains this identical, sequence-verified peptide, ensuring uniformity across all experimental replicates.

Purity & Analytical Verification (HPLC & MS)

Every batch of IGF-1 LR3 supplied by Revo Peptide undergoes rigorous analytical testing prior to release. Peptide purity is confirmed at ≥98% — with many lots achieving >99% purity — using reverse-phase High-Performance Liquid Chromatography (RP-HPLC). Identity is independently confirmed via mass spectrometry (MS), ensuring the molecular weight and sequence integrity of each vial match the certified reference standard. Certificates of Analysis (CoA) are available upon request and accompany bulk orders as standard practice. Researchers can order with full confidence in the analytical traceability of every vial.

Quality Control & Lyophilization Integrity

Revo Peptide employs pharmaceutical-grade lyophilization protocols across all 100 vials in this bulk pack. Each vial is individually processed, stoppered, and sealed under controlled conditions to preserve structural integrity and maximize shelf stability. Lyophilization eliminates residual moisture that could otherwise compromise peptide conformation or potency over time. Batch-level quality control records are maintained for full traceability, and inter-vial consistency is verified to ensure reproducible research outcomes across all 100 units.

Safety, Handling & Laboratory Precautions

IGF-1 LR3 is supplied exclusively as a research-grade lyophilized peptide. Standard laboratory safety protocols must be observed at all times when handling this material. Researchers should wear appropriate personal protective equipment (PPE), including gloves, lab coat, and eye protection. This peptide is not classified as a biohazard; however, standard good laboratory practice (GLP) guidelines apply. Avoid exposure to repeated freeze-thaw cycles post-reconstitution. This product is strictly for in vitro and preclinical in vivo research use by qualified personnel in licensed laboratory settings.

Reconstitution, Packaging & Storage

Each vial contains 1mg of lyophilized IGF-1 LR3 and should be reconstituted using sterile, bacteriostatic, or ultrapure water appropriate for the intended research application. Reconstitution volume should be determined by the researcher based on the desired working concentration for their specific assay or protocol. Once reconstituted, aliquot and store at −80°C for long-term stability, or at 4°C for short-term use within 72 hours. Avoid repeated freeze-thaw cycles. The 100-vial bulk pack is shipped with appropriate cold-chain packaging to maintain product integrity during transit.

Intended Research Use & Market Positioning

IGF-1 LR3 is among the most widely studied peptide analogues in the fields of cell biology, endocrinology, and metabolic research. Its reduced IGFBP binding affinity and extended half-life in solution make it a preferred tool for researchers investigating IGF receptor signaling pathways, cell proliferation assays, muscle satellite cell studies, and anabolic signaling cascades in vitro. This 100-vial bulk pack at 50% off is ideally positioned for CROs, university research departments, and biotech companies requiring sustained, cost-effective supply. Revo Peptide’s bulk IGF-1 LR3 for sale represents one of the most competitive pricing options available for high-purity research peptides in this category.
