All that boiling and bubbling and zapping, experienced only in black and white. Much to our enjoyment, in recent years scientific laboratories have experienced an explosion of color. The necessary consumables--tubes, racks, pipette tips, and lab coats--are available in rainbow-colored assortments. Experimental protocols such as DNA sequencing, fluorescent and colorimetric assays, and digitally enhanced electron microscopy, provide results in a multitude of hues. Color, apart from its aesthetic value, often aids greatly in differentiating multiple species.

NOVEX, maker of novel electrophoretic products and a recent addition to the Invitrogen family, currently offers a colorful alternative to traditional monochrome prestained protein standards.
