Specific conductance of 35% (w/v) solution 2µmho/cm. Used in electrophoresis for separation of nucleic acid fragments and proteins. For precision gels used in electro-phoresis and isoelectric focusing. Because of the low acidity levels of our acrylamide, binding of ampholytes is virtually eliminated and fine pH gradients can be established. Fluorescence-free gels are readily prepared. For scanning of gels n the UV region, our Ultra Pure grade acrylamide makes gels with baselines having very low "noise".
