Human growth hormone (GH1) drives longitudinal growth and metabolic regulation through JAK2/STAT5 signaling, making validated bioactivity essential for meaningful experimental outcomes. This tag-free recombinant protein, spanning residues 27–217 of the mature sequence, demonstrates an ED50 below 0.1 ng/ml in Nb2-11 lymphoma cell proliferation assays, corresponding to a specific activity exceeding 1.0 × 10⁷ IU/mg—providing a reliable standard for receptor binding assays, cell-based metabolic studies such as glucose uptake or STAT5 phosphorylation, and antibody development programs requiring authentic conformational epitopes. Endotoxin levels below 1.0 EU/μg satisfy the criteria typical for in vivo pharmacology, supporting use in metabolic disease models where inflammatory confounders must be minimized. Purity exceeding 98% by SDS-PAGE, combined with this endotoxin profile, also provides a suitable basis for structure-function studies and quantitative immunoassay calibration.
