CCK (26-31) (sulfated)

Description: CCK (26-31) is an N-terminal fragment of CCK , a peptide hormone found in the intestine and brain that stimulates digestion, mediates satiety, and is involved in anxiety. The sulfated form of CCK (26-31) inhibits binding of [125I]CCK-33 to guinea pig cortical membranes by 21% when used at a concentration of 0.1 mM.
