Thompson Embedding Mold

This invention is a mold used for embedding mammalian cells in monolayer culture in preparation of sectioning for light or electron microscopy. Tissue culture monolayer embedding molds eliminate the need for traditional BEEM® capsules. The improved molds can be used to transfer the majority of cells from the entire surface of a cover slip to avoid losses of large amounts of cellular information occurring only randomly. In addition, other problems such as surface blemishes caused by air entrapment associated with BEEM® capsules are eliminated.

Advantages:

• The mold yields several individual blocks of resin from a single slip-cover.
• The resin blocks fit directly into a chuck for flat specimens.
• The embedded surfaces are free from blemishes caused by entrapped air.
• The mold uses a minimum amount of resin.
