Phage libraries are usually shipped as 200 µl DMSO stock frozen on dry ice and should be stored in an ultra-low freezer immediately upon receipt.
Any strains or plasmids shipped with the libraries are shipped as bacterial stabs or yeast slants in individual vials in a separate envelope above the dry ice container and should be stored in a refrigerator or cold room.
Some countries prohibit shipments containing dry ice, in which case the library will be shipped at room temperature. In most cases this does not affect the titer, but the library should be titered and used as soon as possible and stored in a refrigerator or cold room rather than being frozen.
All libraries should be titered before use. If the titer varies significantly from that listed in the paperwork shipped with the library contact ABRC. A new aliquot of the library will be shipped free of charge.
