APPLICATOR COMB FOR GEL ELECTROPHORESIS

A fluid applicator device (10) includes an applicator body (14) having a surface that is generally planar. A plurality of aligned applicator teeth (16) extend from said applicator body. Each applicator tooth (16) extends longitudinally from said applicator body (14) along a length from a base (18) of the applicator tooth proximate to the applicator body to a tip (20) of the applicator tooth distal to the applicator body. At least one applicator tooth of the plurality of aligned applicator teeth has a width that is greater at the base than at the tip. A method for depositing a liquid sample on a substrate using the fluid applicator device is also disclosed. The applicator teeth (16) may comprise perforations. The applicator teeth (16) may comprise a hydrophobic flash border surrounding the main applictor tooth body to prevent premature deposition of the sample fluid.
