修飾性PEG保存方法
發(fā)布時(shí)間：2018-4-24修飾性PEG保存方法
修飾性PEG 對(duì)溫度和水分非常敏感，收到貨物后請立刻-15℃或低于-15℃保存。打開包裝前請將產(chǎn)品恢復(fù)至室溫。我們推薦以干粉的方式存放于干燥處。
請勿以溶液形式保存。每次打開包裝瓶后，都需要填充惰性氣體（例如氬氣，氮?dú)猓?/span>
后才能蓋上瓶蓋再保存。
我們強(qiáng)烈建議不要以溶液形式保存修飾性PEG！
如需要分裝請參考下列步驟：
1. 將試劑放置至室溫
2. 將試劑移至充滿惰性氣體的手套式操作箱或類似的充滿惰性氣體的環(huán)境下
3. 按需求分裝
4. 蓋蓋子前每一份都需要充入惰性氣體
5. 每一份分裝后的試劑都需要-15℃或低于-15℃保存直至使用
PRODUCT STORAGE INSTRUCTIONS
Because PEG derivatives are temperature and moisture sensitive they should be stored in a freezer at or below -15℃ upon receipt. Please allow PEG derivatives to equal room temperature before opening. We recommend storing our PEG derivatives as the dry, powder form only and not in any type of solution. Each time the bottle is opened it will need to be back filled with an inert gas (i.e. Argon, Nitrogen) before being stored again.
WE DO NOT RECOMMEND YOU STORE PEG PRODUCTS IN SOLUTION ！
If your reagent requires rebottling please follow these steps:
Allow reagent to equilibrate to room temperature
While reagent is thawing prepare glove box or another suitable area for packaging which will allow for an inert atmosphere
Flush the repackaging enclosure with an inert gas (i.e. Argon, Nitrogen)
Repackage into desire aliquots
Flush each aliquot with inert gas before closing
Store each aliquot at or below -15℃ until ready to use.
