Non-breakable, electrically insulating sample well inserts for slab electrophoresis

摘要

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.
