Big Endothelin-1 (22-38), human is derived from human, is the 22-38 fragment of Big Endothelin-1 (ET-1) (1-38). Big ET-1 (1-38) is a propeptide of ET-1, which has potent and long-lasting vasoconstrictor effects, equips a specific enzymatic cleavage of the 38 amino acid chain to form ET-1 (1-21) and the C-terminal fragment Big ET-1 (22-38).

Urocortin III (human) is a corticotropin-releasing factor (CRF)-related peptide. Urocortin III (human) preferentially binds and activates CRF-R2 and has a discrete central nervous system and peripheral distribution. Urocortin III (human) selectively binds to type 2 CRF receptors with Ki values of 13.5, 21.7, and >100 nM for mCRF2β, rCRF2α, and hCRF1, respectively. Urocortin III (human) mediates somatostatin-dependent negative feedback control of Insulin (human) secretion.

Rusalatide acetate (TP508 amide acetate), a regenerated peptide, alleviates radiation-induced gastrointestinal injury by activating stem cells and protecting recess integrity.
