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".
High purity crosslinking monomer used for precision PAGE. Also suitable for UV scanning gels. Crosslinking monomer used especially with acrylamide.
Conductivity, 2% w/v, 20-25°C <5.0 μS/cm = μmho了解更多
The convenience and safety of premixed acrylamide and methylenebisacrylamide is now available with Polysciences’ high quality standards. Acrylamide (#00019) and N,N’-methylene bisacrylamide (#00719) are combined in a readily soluble form in exact proportions. Each batch is pretested. Each unit (bottle) contains 30 grams of solids. Add deoinized water to the graduated bottle to make 100ml or 30% stock solution and store for 1 month at 4°C. No handling of toxic powders required.

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.了解更多
Buffer for fixatives for light and electron microscopy; e.g., osmium tetroxide, formaldehyde, glutaraldehyde, Karnovsky’s fixative.了解更多
