| 产品介绍 |
Purity > 97 % by SDS-PAGE and HPLC analyses Additional sequence information This product is the mature full length protein from aa 24 to 129. The signal peptide is not included. Function Inhibits gastrointestinal motility and gastric acid secretion. Could function as a structural component of gastric mucus, possibly by stabilizing glycoproteins in the mucus gel through interactions with carbohydrate side chains. |
| 生物活性 | Fully biologically active when compared to standard. The ED₅₀ as determined by a chemotaxis bioassay using human MCF-7 cells is less than 10 ng/ml, corresponding to a specific activity of > 1.0 × 10⁵ IU/mg. |
