  1. Acrylamide, Chemzymes Ultra Pure®

    Acrylamide, Chemzymes Ultra Pure®

    Starting at: €71.00

    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".

  5. Agarose, Molecular Biology Grade

    Agarose, Molecular Biology Grade

    Starting at: €160.00

    Agarose is a natural complex polysaccharide isolated from agar or agar-bearing marine algae. It forms a clear gel matrix that is very useful for electrophoresis, immuno-electrophoresis and immunodiffusion. It is ideally suited for electrophoretic separation of proteins and nucleic acids and for PCR product analysis.
