Agarose LE Powder

Features

• Multi-purpose, high purity

• Green Choice, free from organic solvents

• Enhanced resolution and clarity

• Low EEO / increase electrophoretic mobility

• RNase, DNase and Protease free

EMS Agarose LE is a highly purified agarose, suitable for a variety of molecular biology applications. It is refined using an advanced process that excludes the use of organic solvents, yielding a cleaner end-product with a significantly reduced environmental impact. EMS Agarose LE can be used for analyses of proteins and nucleic acids of various sizes (150 bp to 6 kbp).

It's low EEO (≤ 0.13 -mr) promotes increased electrophoretic mobility, yielding improved resolution and shorter run times. This also allows macromolecules and larger particles (subcellular fragments, viruses, etc.) to migrate more freely through the gel matrix. The consistently low EEO also provides a reduction in band distortion (caused by counterflow) that can result from the presence of excessive sulfate-rich negative ions.

EMS Agarose LE is widely used for nucleic acid electrophoresis (analytical and preparative), protein electrophoresis (including radial immunodiffusion) and various blotting protocols. It is easily soluble, free of nucleases, and easy to use. It is highly transparent (forms a clear, colorless solution at 1g:100ml H₂O), and exhibits exceptionally low absorption of chemical staining agents. Pore size can be adjusted by simple modifications to the concentration ratio.

Formulated for high gel strength and integrity, EMS Agarose LE exhibits exceptional thermal stability and mechanical resistance, ensuring safe, easy handling, regardless of whether a denaturing agent has been added.

Researchers trust EMS Agarose LE to meet their electrophoretic needs for a variety of applications. Now the same EMS agarose is available in a convenient, no mess tablet.

EMS Agarose LE is refined in an advanced process that excludes the use of organic solvents. The result is a cleaner end product with significantly reduced environmental impact. The EMS agarose can be used for analyses of nucleic acids from 150 bp to 6 kbp, protein electrophoresis and various blotting protocols.

The low EEO of the EMS agarose promotes increased electrophoretic mobility, yielding improved resolution and shorter run times. This also allows macromolecules and larger particles (subcellular fragments, viruses, etc.) to migrate more freely through the gel matrix. The consistently low EEO reduces band distortion (caused by counterflow) that can result from the presence of excessive sulfate-rich negative ions.

The quick dissolving EMS EZ Pack™ tablet contains 0.5g (500 mg) of EMS Agarose LE, eliminating the hands-on time and inaccuracies normally associated with weighing. Use of the tablet is not only convenient and cleaner, it also provides better consistency and reproducibilty gel to gel. Gel preparation is simple – add the desired number of tablets to electrophoresis buffer, allow to sit for two minutes and then heat and pour as usual. The resulting gels are highly transparent, have exceptional thermal stability (ensuring safe and easy handling) and exhibit exceptionally low absorption of chemical staining agents.

EMS EZ Pack™ Agarose Tablets are supplied in convenient blister packs for safe, clean dispensing.

Antibody Diluent

Buffer for diluting your primary and secondary antibodies, especially if they were stored for a while, even at -20 in glycerol, or in refrigerator. Nonspecific binding of the antibodies, negative effects of disturbing substances and low or medium affinity cross-reactivities of the antibodies will be minimized, making your result more reliable. Excellent for IHC (frozen and formalin sections), flow cytometry on fixed cells, Western Blot and other immune assays.

When used in pathology, in also greatly reduces non-specific reactivity of human serum components and immunoglobulins in tissue, vessels and cells with mouse antibodies used on section.

For especially "trouble"-giving antibodies, as well as for in situ PCR applications, this dilutent may also be used as a washing buffer, preventing secondary binding of your analystes during washing.
