Pasireotide (SOM230), a long-acting cyclohexapeptide somatostatin analogue, can improve agonist activity at somatostatin receptors (subtypes sst1/2/3/4/5, pK_i=8.2/9.0/9.1/<7.0/9.9, respectively). Pasireotide can suppress GH, IGF-I and ACTH secretion, indicating potential efficacy in acromegaly and Cushing's disease. Pasireotide also exhibits antisecretory, antiproliferative, and proapoptotic activity.

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.
