IGF-1 Proteins

Vorex’s IGF-1 proteins category provides research-grade insulin-like growth factor analogs, including IGF-1 LR3 and IGF-DES, for in-vitro laboratory investigation. Each protein is synthesized to high specification and verified to ≥98% purity by independent third-party testing, with a Certificate of Analysis available on every product page, and is supplied as a stable lyophilized powder in sealed vials. Orders ship tracked across the United States with appropriate handling. IGF-1 analogs are widely studied in cellular growth and signaling research, and Vorex supplies them with the documented purity and batch-to-batch consistency reproducible experiments require. All IGF-1 proteins are sold strictly for laboratory and scientific research use and are not intended for human or veterinary use, consumption, or application.

Frequently Asked Questions

Essential information about our research-grade peptides and quality standards.

Peptides are short chains of amino acids linked by peptide bonds, typically consisting of 2-50 amino acids. They serve as the building blocks of proteins and play crucial roles in biological processes.

Research peptides are synthesized versions of naturally occurring peptides, manufactured to precise specifications for use in scientific studies.

Key characteristics: High purity (≥98%), lyophilized form for stability, accompanied by Certificates of Analysis (COA), and manufactured under strict quality control protocols.

Peptide purity refers to the percentage of the target peptide present in a sample, measured via High-Performance Liquid Chromatography (HPLC).

Our Standard: All our research peptides maintain ≥98% purity, verified by third-party laboratory testing and documented in our Certificates of Analysis.

Higher purity is critical for research because impurities can interfere with experimental results and compromise the reproducibility of studies.

All products are supplied in lyophilized powder form within sterile, sealed vials. This format provides:

Maximum stability: Extended shelf life compared to liquid solutions
Precise measurement: Researchers can work with desired quantities
Contamination protection: Sealed vials prevent environmental exposure
Shipping durability: Powder form is more stable during transit

Lyophilized peptides:

Store at -4°F for long-term storage (up to 24 months)
Store at 36-46°F (refrigerated) for short-term storage (up to 3 months)
Keep away from light, moisture, and repeated temperature fluctuations

We supply research-grade peptides to:

Academic and university research laboratories
Pharmaceutical and biotechnology companies
Independent research institutions
Licensed professionals conducting legitimate scientific research

We maintain rigorous quality control through a multi-step verification process:

HPLC Analysis: Every batch tested to verify ≥98% purity
Mass Spectrometry: Molecular weight confirmation for peptide identity
Third-Party Testing: Independent laboratory verification
