General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |
||
About Packaging | 1. The packaging of the product may be reversed during transportation, cause the high purity compounds to adhere to the neck or cap of the vial.Take the vail out of its packaging and shake gently until the compounds fall to the bottom of the vial. 2. For liquid products, please centrifuge at 500xg to gather the liquid to the bottom of the vial. 3. Try to avoid loss or contamination during the experiment. |

The prevention of elastase-induced emphysema in hamsters by the intratracheal administration of a synthetic elastase inhibitor bound to albumin microspheres.[Pubmed:3848290]
Am Rev Respir Dis. 1985 Jul;132(1):159-63.
The peptide, succinyl-alanyl-alanyl-prolyl-valine chloromethylketone (SPCK), a synthetic inhibitor of elastase, was covalently attached to human albumin microspheres (HAM) and administered intratracheally to hamsters 15 min and 8 h prior to the instillation of porcine pancreatic elastase. Pressure-volume relationships and histologic examination of excised lungs after 4 wk showed complete protection from emphysema when SPCK-HAM was administered either 15 min or 8 h before elastase exposure. Concurrent experiments with free SPCK showed that protection was achieved only if elastase was administered within 15 min after the instillation of SPCK. Extending this period to 8 h not only led to a failure of free SPCK to prevent emphysema but actually resulted in more extensive air-space enlargement. The prolonged effectiveness conferred by the attachment of SPCK to a biodegradable carrier should reduce the frequency with which it would have to be administered for the therapeutic intervention of emphysema and should minimize any toxic side reactions.
