Used in laboratory research to measure levels of growth hormone-releasing polypeptides in biological samples from mice. Commonly applied in endocrinology and metabolic studies to investigate growth hormone regulation, pituitary function, and the effects of experimental treatments on the somatotropic axis. Enables quantitative analysis of peptide activity in serum, plasma, or cell culture supernatants. Widely used in preclinical studies related to growth, aging, and muscle development. Not intended for diagnostic or therapeutic use.
