Product Information
| Description: | SFTI-1 is a head-to-tail bicyclic peptide with a disulfide bond that inhibits the serine protease trypsin with subnanomolar levels of inhibition constants. It can be used as a protease inhibitor or as a molecular grafting scaffold. In addition, by introducing a known tetrapeptide pharmacophore into the bicyclic SFTI-1, a potent ligand for melanocortin can be created. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
