Blotter pad for electrophoresis

A blotter assembly for use in electrophoresis, comprising:

• a blotter block with an upper surface and a lower surface, wherein:
• the upper surface of the blotter block comprises a first and second upwardly extending projections on opposite sides of the blotter block;
• and
• the lower surface of the blotter block comprises a first and second elongated raised portions that are parallel to each other and extend along the length of the lower surface towards opposite edges of the blotter block;
• a closed-cell silicone blotter pad configured to be removably attached by adhesive to the lower surface of the blotter block, wherein, when attached, the blotter pad is restrained against accidental movement relative to the blotter block;
• and
• a blotter paper configured to be removably attached by adhesive to the closed-cell silicone blotter pad, wherein:
• the blotter paper is restrained against accidental movement relative to the closed-cell silicone blotter pad when the blotter paper is attached to the closed-cell silicone blotter pad;
• and
• the raised elongated portions of the blotter block are configured to assist in aligning the blotter paper relative to the closed-cell silicone blotter pad.
