HGH (Somatropin) 36 IU

Somatropin is recombinant human growth hormone (191 amino acids), produced in cell-expression systems rather than extracted from biological sources. In the research context, it serves primarily as a reference standard: laboratories studying GH-axis physiology, assay developers calibrating immunoassays, and groups benchmarking novel secretagogues all require a well-characterized full-length hormone against which to compare experimental compounds. Its analytical profile is among the most demanding in peptide science — identity confirmation, purity by multiple orthogonal methods, aggregate analysis, and bioactivity verification — reflecting its status as a complex folded protein rather than a short synthetic peptide. This 36 IU presentation provides a substantial reference quantity for extended calibration programs, longitudinal assay-validation studies, and multi-site research collaborations requiring a single consistent standard. Handling follows cold-chain and reconstitution guidance appropriate to recombinant proteins. Reference-standard applications demand the most rigorous analytical characterization in the catalog, including orthogonal purity methods. For laboratory research use only. Not for human or veterinary use.
