Description_x000D_ General description_x000D_ Precast agarose gels are designed for high resolution separation of nucleic acids, producing sharp RNA bands with low background fluorescence. Precast gels are individually foil sealed in plastic trays and are supplied in a box of twenty._x000D_ Gel size: 6.0 × 9.5 cm, 5.5 mm thick_x000D_ Cassette size: 6.8 × 10.2 cm container tray (fits common horizontal electrophoresis units)_x000D_ Well orientation: 8-well, portrait style_x000D_ Application_x000D_ Precast Agarose Gels has been used for the electrophoresis of purified PCR products._x000D_ Precast agarose gels are designed for high resolution separation of nucleic acids, producing sharp DNA and RNA bands with low background fluorescence. Precast gels are individually foil sealed in plastic trays that help eliminate contamination from equipment and handling. Gels can be electrophoresed right in the plastic tray._x000D_ TBE - agarose gels are available in two common concentrations (1% and 4%) for DNA electrophoresis. Ethidium bromide (0.5 μg/ml) is included in the TBE-agarose gels for easy visualization. TBE-agarose gels are available in 8, 20 and 24 well formats. The separation range for the 1.0% gel is 500-1000 bp and 8-1000 bp for the 4% gel._x000D_ MOPS - agarose gels (1.25%) are available without denaturants (e.g. formaldehyde or glyoxal) for the analysis of total RNA, in vitro RNA transcripts, and Northern blotting. RNA electrophoresis usually does not interfere with staining. If significant secondary structure is suspected, the RNA should be denatured by a method listed in the product insert. The separation range for the 1.25% MOPS gel is 0.25-10 kb._x000D_ Packaging_x000D_ Package of 20 individually foil-wrapped gels._x000D_ Other Notes_x000D_ DNA agarose gels contain 1× TBE buffer (0.089 M Tris-borate, pH 8.3, 2 mM EDTA) and 0.5 mg/ml ethidium bromide._x000D_ RNA agarose gels contain 1× MOPS (20 mM MOPS, 5 mM sodium acetate, 1 mM EDTA and 1 mM EGTA, pH 7.0)_x000D_ Quality_x000D_ No detected DNase or RNase activity_x000D_ Physical form_x000D_ Gel size: 6.0 × 9.5 cm, 5.5 mm thick_x000D_ Cassette size: 6.8 × 10.2 cm container tray; fits common horizontal electrophoresis units_x000D_ Sample format: 8-well (portrait), 20-well (landscape), 24-well (2 × 12 well portrait)
