The plates are packed horizontally in a Styrofoam box with dry ice, surrounded by ice packs and Styrofoam chips. This arrangement keeps the plates frozen, horizontal and immobile. The carrier is Federal Express or occasionally Nippon Express for international orders.

We use 96 well Thermo Scientific Matrix 1.4 ml -catalog# 4247 racks with Matrix Cap Strips catalog# 4415. Please contact us if you have the need to use any other 96 well plate or format.

The DMSO solutions will remain frozen to ~10*C. All solutions are prepared at room temperature and stored frozen at -20*C or lower and kept under nitrogen. On receipt, transfer the plates to a freezer and store them horizontally.

We ensure that the compounds in our collections are greater that 95% pure, however, a few macromolecular compounds are mixtures of isomers as referenced in the Merck Index. Examples are Bacitracin, Bleomycin, Colistin, Enoxiparin, Gramicidin and Teicoplanin. The solutions are stable. A few compounds, if kept at room temperature for long periods, may decompose through oxidation or addition reactions with DMSO. After use and prior to storage:

1. Flush the wells containing the compound solutions with nitrogen or argon. This is accomplished by use of a gently stream of the inert gas as the wells are recapped.

2.Store the resealed plates at -20C or lower.

3. When the plates are retrieved, do not remove the caps until the plates are at room temperature.

4. Do not attempt to store solutions diluted in buffer; precipitation will occur. Under such conditions the compounds in the collection should be stable (>98%) for several years.
