DETAILS

Description (English)
Packaging
5 g in poly bottle
Reconstitution
To recover the pure product from the suspension:(1)Thaw the frozen suspension and filter the solid. (2) Rinse bottle with a few milliliters of base-washed (aqueous Na2CO3) ethyl acetate. (3) Use the rinsing to wash the solid. (4) Collect solid. (5) To further collect more product from the filtrate: extract filtrate with equal volumes of base-washed (aqueous Na2CO3) ethyl acetate (repeat three times). (6) Dry the ethyl acetate extract over MgSO4. (7) Evaporate the solvent - DO NOT HEAT! (8) Combine solids collected from the suspension and the filtrate. Pure crystals should be stored at -78° C. A suspension of the product in phosphate buffer is stable at 0° C.
Physical form
A suspension in phosphate buffer.

Reconstitution
从悬浮液中回收纯产物: (1) 将冰冻悬浮液融化并过滤出固体。(2) 用几毫升碱性(含水 Na2CO3)乙酸乙酯洗液冲洗瓶子。(3) 用清水洗涤固体。(4) 收集固体。(5) 从滤出液中进一步收集更多产物:用等体积碱性(含水 Na2CO3)乙酸乙酯洗液抽提滤出液(重复三次)。(6) 将乙酸乙酯抽提物置于 MgSO4 上干燥。(7) 待溶剂蒸发-不要加热!(8) 合并从悬浮液和滤出液中收集的固体。纯晶体应保存于 -78°C。产物的磷酸盐缓冲液悬浮液在 0°C 时稳定。
Physical form
