Description

Physical form

A suspension in phosphate buffer.

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 filtratewith 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.
