HGH (Somatropin)

HGH (Somatropin) is supplied as a laboratory research reference material intended solely for in-vitro and laboratory investigations. Cataloged under SKU HGH and CAS 12629-01-5, this item is offered as a white to off-white lyophilized powder with a documented purity of not less than 98% by HPLC, with lot-specific values recorded on the accompanying Certificate of Analysis.

Structurally, HGH (Somatropin) is a full-length synthetic human growth hormone polypeptide comprising 191 amino acid residues, corresponding to the molecular formula C990H1529N263O299S7 and a calculated molecular weight of approximately 22,125 g/mol. The sequence begins at the N-terminus with Ser-Tyr-Asn-Thr-His-Glu-Thr-Ile-Cys, and its seven sulfur atoms reflect four cysteine residues that participate in two intramolecular disulfide bridges characteristic of the native fold. The polypeptide is produced synthetically and reconstitutes the primary structure of the pituitary-derived 22 kDa isoform used across reference chemistry work.

As a reference item, HGH (Somatropin) is well suited to analytical characterization workflows including RP-HPLC and SEC-HPLC purity profiling, UV absorbance quantitation, peptide mapping by tryptic digest with LC-MS readout, intact-mass confirmation by ESI-MS or MALDI-TOF, SDS-PAGE and isoelectric focusing, circular dichroism for secondary-structure benchmarking, and Karl Fischer or residual solvent testing. Its molecular weight, formula, and sequence anchors make it a convenient identity marker for method development, calibration curves, and instrument qualification in laboratories handling recombinant or synthetic protein standards.

Formulators and analysts should treat the lyophilized cake as a hygroscopic solid; storage guidance, reconstitution behavior, and stability data should be interpreted against the lot-specific Certificate of Analysis, which documents identity, purity, appearance, and associated release testing for each batch of HGH (Somatropin).

Published scientific literature has examined HGH (Somatropin) in preclinical research; PEPTIDE.Power makes no therapeutic, diagnostic, or efficacy claims regarding this material and provides no administration or dosing guidance. This material is not a drug, supplement, cosmetic, or food, and is not for human or veterinary use, injection, or ingestion. Identity and purity are documented on the lot-specific Certificate of Analysis, available on request.

Supplied as a lyophilized (freeze-dried) powder in a sealed vial. A research reference material - not a finished product and not a delivery device. Net contents per unit are shown in the product options.

Store the sealed lyophilized powder at -20 C, protected from light and moisture. After reconstitution for laboratory use, keep cold and use promptly. Handle per standard laboratory practice; a Safety Data Sheet (SDS) is available on request.
