Cholecystokinin (Cholecystokinin-33 (human); CCK-33 (human)) is a secreted peptide hormone. Cholecystokinin activates CCK-A receptors to reduce food intake and induce satiety, and activates CCK1 receptors to mediate insulin release. Cholecystokinin mediates anti-inflammatory and renoprotective effects on diabetic kidney macrophages through CCK-1 receptors, and limits diabetic kidney injury through CCK-2 receptors. Cholecystokinin can be used in research on diabetic nephropathy and obesity.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
