Research Overview
Histatin-5
Histatin-5 is a major salivary defense peptide that can kill Candida species and influence oral microbial communities. It is also investigated for wound-healing and xerostomia-associated oral infection models.
hGHRH(1-44)
Human GHRH(1-44) amide has been used extensively to characterize hypothalamic control of pituitary somatotrophs and the downstream GH/IGF-1 axis. It remains a standard comparator in studies of GHRH agonism, secretion dynamics, and receptor pharmacology.
