Small bag with absorbed EtBr safely disposed in solid waste One kit removes 500 mg of EtBr from solutions The EtBr Green Bag Kit allows rapid and trouble-free concentration of ethidium bromide from large volumes of solutions into a small “tea bag” which is then conveniently…

Low EEO for complete resolution of bands >500 bp Molecular Biology Grade Highly purified, strict quality testing procedures Tested for transfer to membrane Molecular Biology Grade QA-Agarose is a standard gelling temperature agarose with very low EEO (electroendosmosis) values…

Molecular biology grade Formamide is used in molecular biology as a denaturing agent in gel electrophoresis or hybridization experiments. In the latter case, the role of formamide is to decrease the temperature necessary for the reassociation of complementary nucleic acids. Store at room…

Molecular biology grade Tween 20 is a non-ionic surfactant used in blocking solutions. Store at room temperature.

For SDS-PAGE protein gels use the following standard dye mix: 2x solution of Bromphenol blue, urea, SDS, β -mercaptoethanol.

Molecular biology grade TAE buffer (Tris-acetate-EDTA buffer) is used for the electrophoresis of nucleic acids and gives excellent resolution of the DNA bands under low voltage. Store at room temperature.

Ultrapure grade prepared from highly purified acrylamide (4X) and bis-acrylamide (2X) using deionized ultra-filtered water. Store at 4°C and protect from light. Final ratios: 19:1 is optimal for sequencing gels and also for separation of peptides 29:1 for sequencing gels and the separation…

Molecular biology grade Tris (Tris-(Hydroxymethyl) aminomethane) buffer (pH 8-9) is used for the preparation of buffer solutions for restriction enzymes or nucleic acid modifying enzymes. Tris base should be stored dry at room temperature.

In-gel manipulation, no gel purification necessary Finer sieving properties vs. standard melt agarose High clarity Suitable for viral plaque assays QA-Agarose Low Melting has finer sieving characteristics than standard melt agaroses and is for separation of DNA/RNA fragments…

For the analysis of small nucleic acid fragments Separates from 20 to 2000 bp High concentrations up to 6% Resolves fragments differing in size by 2% Avoids need for PAGE Dissolves easily in a microwave High Resolution QA-Agarose offers extremely fine sieving…

Separate fragments from 200 bp up to 50 kb by conventional electrophoresis For preparative DNA and RNA electrophoresis Concentrations between 0.4 and 6% Suitable for use in pulsed field gel electrophoresis Improves separation of very large fragments QA-Agarose Multipurpose…

10x solution of Bromphenol blue, xylene cyanole FF, and glycerol

Molecular biology grade TBE (Tris Borate EDTA buffer) is a widely used electrophoresis buffer. This optimized buffer offers a high level of resistance to the Joule effect which occurs during prolonged high voltage electrophoretic migrations.
