2 3 Nucleic Acids Electrophoresis Agaroses EuroClone offers a complete selection of high quality agaroses for standard and specific electrophoresis appications. GellyPhor LE GellyPhor LM GellyPhor ULTRA GellyPhor HR GellyPhor PFGE DNA separation 1-50 kb DNA/RNA separation 1 kb DNA/RNA separation 1 kb -. DNA separation bp Blotting - - DNA finger printing Nucleic Acid Recovery GellyPhor LE GellyPhor LE is ideal for general nucleic acids preparative and analytical gel electrophoresis as well as for blotting. This gel sharply resolves the different DNA fragments to be analyzed and provides consistent resolution from batch-to-batch. It forms high strength gels with low background upon ethidium bromide staining. Due to the low electroendosmosis value (EEO) of GellyPhor LE the DNA has a high electrophoretic mobility allowing shorter running time.

This molecular biology grade agarose produces gels with greater sieving properties and higher clarity than standard melting temperature agarose. The low melting temperature of GellyPhor LM makes it ideal for preparative nucleic acids electrophoresis, while its low geling temperature is perfect for cloning of tissue culture cells and viral plaque assays.

3 Nucleic Acids Electrophoresis 3 GellyPhor HR GellyPhor HR is a molecular biology grade standard melting temperature agarose, that yields strong gels for fine resolution of small nucleic acids fragments. Performance testing of GellyPhor HR ensures fine resolution of DNA fragments up to 1000 bp, though this agarose is capable of finely resolving DNA fragments ranging from 10 bp up to 1200 bp. GellyPhor HR is designed for analytical electrophoresis. Gelling Temperature (dynamic measurement in 3% solution) Gel strength 35.5 C Electroendosmosis (-mr) 0.12 Sulphate 0.11% Moisture 7% 600 g/cm 2 (for a 1.5% gel) 1500 g/cm 2 (for a 3% gel) Melting Temperature (3%) 80 C none detected Ranges of separation: 1.8% bp 3% bp 4.5% bp These ranges are approximate and have been calculated in TAE Buffer. To achieve the best resolution of GellyPhor HR gels, they should be stored at 4 C- 8 C for 30 minutes before use. Format EMR GellyPhor HR 100 g Five years at GellyPhor ULTRA GellyPhor ULTRA is an intermediate melting temperature agarose that provides twice the resolution capabilities of the finest sieving agarose products. You can resolve DNA fragments, PCR and RT-PCR products differing in size by 2%, in the range of 200 bp to 800 bp, by horizontal gel electrophoresis (for example, a 200 bp DNA fragment can be separated from a 204 bp fragment). Using fast run protocols, DNA fragments differing in size by 1% can be resolved in as little as 1.5 hours in a 20 cm long horizontal or vertical gel format. GellyPhor ULTRA agarose gels (2% to 4%) approximate the resolution of polyacrylamide gels (4% to 8%). Format EMR GellyPhor ULTRA 125 g Five years at Gelling Temperature (dynamic measurement in 3% solution) 36 C Gel strength (3%) 400 g/cm 2 Electroendosmosis (-m r ) Moisture 10% Melting Temperature (3%) 75 C none detected GellyPhor PFGE GellyPhor PFGE is a very high gel strength, low EEO, standard gelling temperature agarose. Due to its high gel strength, this agarose can be used for the preparation of low percentage gels for the analysis not only of high molecular weight nucleic acids (such as chromosomes), but also of largesized particles such as viruses and ribosomes.

4 3 Nucleic Acids Electrophoresis Acrylamides For the separation of oligonucleotides with a small number of bases, acrylamide gels with a small pore size are used. The pore size is determined by the total concentration of acrylamide and the ratio of Acrylamide/Bisacrylamide. For the sequencing of nucleic acids a ratio of Acrylamide/Bisacrylamide 19:1 is used. EuroClone offers a ready-to-use 40% Acrylamide/Bisacrylamide 19:1 mix. Format EMR Acrylamide/Bisacrylamide 19:1 (solution 40%) 500 ml EMR Acrylamide/Bisacrylamide 19:1 (solution 40%) 1 L Buffers and reagents for DNA electrophoresis EuroSafe Nucleic Acid Stain EuroSafe Nucleic Acid Staining Solution (20,000x) is a safe nucleic acid stain, an alternative to the traditional ethidium bromide (EtBr) stain for detecting nucleic acid in agarose gels. It emits green fluorescence when bound to DNA or RNA. This stain has two fluorescence excitation maxima when bound to nucleic acid, one centered at 309 nm and another at 419 nm. In addition, it has one visible excitation at 514 nm. The fluorescence emission of EuroSafe bound to DNA is centered at 537 nm. EuroSafe is as sensitive as EtBr. Compared to EtBr, known as a strong mutagen it causes much fewer mutations in the Ames test. In addition, EuroSafe Nucleic Acid Staining Solution (20,000x) has a negative result in mouse marrow chromophilous erythrocyte micronucleus test and mouse spermary spermatocyte chromosomal aberration test.

5 Nucleic Acids Electrophoresis 3 DNA Ladders EuroClone has three different DNA Ladders for sizing and approximate quantification of double-stranded DNA fragments such us PCR products. The Ladders have extremely sharp bands and reference bands with higher DNA content for easy orientation. SHARPMASS 50 - DNA LADDER This 50 bp DNA-Ladder is composed of 13 chromatography-purified individual DNA ranging from 50 to 1000 bp. The 500 bp and 250 bp fragments have a higher DNA content and serve as size references. SHARPMASS DNA LADDER This Ladder includes many plasmids fully digested by restriction enzymes. This process leads to the creation of 10 bands suitable for use as molecular weight standards for agarose gel electrophoresis. The digested DNA includes fragments ranging from 100 to 1000 bp. The 500 bp fragment has enhanced brightness and can be used as reference point.

It is designed to show virtually uniform spacing over a wide fragment range. The Ladder allows sizing and concentration estimate of DNA fragments on agarose gels generated by PCR or restriction digest. The fragment mix is supplied in ready-to-use format containing orange and blue tracking dyes. SHARPMASS 1 - DNA LADDER This Ladder includes many plasmids fully digested by restriction enzymes. This process leads to the creation of 13 bands suitable for use as molecular weight standards for agarose gel electrophoresis. The digested DNA includes fragments ranging from 250 to bp. For an easier reference, the fragment of 1000 bp generates a three times brighter band and the bp generates a two times brighter band. One year at -20 C Blue Ice 19
