Abstract
Sharkstooth combs for use in slab electrophoresis for holding samples above the gel prior to being separated in contiguous lanes are formed of a metallic core sheathed in a surface coating to render such a comb electrically insulating. The metallic core provides the comb with the strength needed to prevent breakage of the teeth, which is otherwise a problem due to the thinness of the comb.
