HGH FRAG 176-191 5MG

El Toro HGH Fragment 176–191 is a synthetic peptide fragment derived from the C-terminal region of human growth hormone (hGH). It is supplied exclusively for in-vitro and laboratory research to assist scientists studying peptide signalling, metabolic pathways, and amino acid sequence–function relationships.
Each vial contains 5 mg of lyophilised HGH Frag 176–191, manufactured under ISO-accredited clean-room conditions to ensure analytical integrity, reproducibility, and high purity.

Chemical Background / Research Profile

The chemical formula of HGH Fragment 176–191 is C₇₈H₁₂₃N₂₃O₂₃S₂, with a molecular weight of approximately 1817 g/mol.
This fragment corresponds to amino acids 176–191 of the human growth hormone polypeptide chain. It does not include the full growth hormone molecule but rather a short peptide sequence representing its terminal region.

In research applications, HGH Fragment 176–191 is used to:

• Examine receptor binding kinetics and sequence-specific signalling.

• Explore GH-related metabolic processes under controlled in-vitro conditions.

• Model peptide–enzyme interactions and protein breakdown pathways.

• Investigate structure–function relationships between peptide fragments and larger protein hormones.

Due to its structural simplicity and defined sequence, HGH Frag 176–191 serves as a valuable model for understanding amino acid sequence functionality and signal modulation in cell-based research systems.

Purity and Quality Assurance

Each batch of El Toro HGH Fragment 176–191 is verified to a minimum purity of ≥ 98 %, tested by High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) for molecular accuracy and batch consistency.
Manufacturing is conducted under Good Manufacturing Practice (GMP) and Good Laboratory Practice (GLP) guidelines in ISO-certified facilities.

Every vial is sealed under sterile conditions and supplied with a Certificate of Analysis (CoA) detailing batch number, purity data, and expiry date, ensuring full traceability for laboratory documentation.

Laboratory Handling and Storage

• Store at 2–8 °C, protected from light and moisture.

• For extended storage, freezing at –20 °C is recommended.

• Allow the vial to reach ambient temperature before opening to prevent condensation.

• Reconstitute with sterile bacteriostatic water or an appropriate laboratory solvent under aseptic conditions.

• Avoid repeated freeze–thaw cycles and dispose of unused solutions in accordance with institutional biosafety procedures.

Researchers should handle all materials using standard PPE (gloves, coat, and protective eyewear) within authorised research facilities.
