DNA Kit

Brand:

Cleaver Scientific

This simple kit will enable you to teach the principles behind gel electrophoresis. The kit contains five DNA samples labelled A to E, two of which are identical, with enough reagents to run two sets of six gels. The students will be able to run their own agarose gel and view the DNA after the samples have migrated through the gel. The DNA samples can be viewed on a standard UV transilluminator or using the totally sage blue light LED devices.

dsRNA Ladder – 25 gel lanes

Brand:

New England Biolabs

The dsRNA Ladder is a set of 7 annealed double-stranded RNA molecules produced by in vitro transcription of 14 linear DNA templates. The ladder sizes are: 500, 300, 150, 80, 50, 30 and 21 base pairs. All have 2-base, 3´ extensions. The 80 base pair fragment is at double intensity to serve as a reference point.

This ladder is suitable for use as a size standard in dsRNA and RNAi analysis on both non-denaturing polyacrylamide and agarose gels.

Dye Kit

Brand:

Cleaver Scientific

This simple kit will enable you to teach the principles behind gel electrophoresis without the need to view the samples on a UV or blue light transilluminator. The kit contains five dye samples labelled A to E with enough reagents to run two sets of six gels. Vial A contains a dye marker consisting all 4 dyes. The other vials B to E contain a single dye. When the samples are loaded into a gel and run on an electrophoresis unit the students will be able to watch the different coloured dyes separate by the size of the molecules, so simulating how DNA separates by different molecular weight.

proBLUE DNA Stain

Brand:

Cleaver Scientific

Agarose electrophoresis of DNA requires a staining step in order to visualise the DNA fragments. This can be done safely using methylene blue solution. Methylene blue binds to negatively charged DNA making DNA visible as blue bands within agarose following electrophoresis. Methylene blue solution is provided as a 10x concentrate. To use, dilute 10x concentrate by mixing one part of methylene blue with nine parts of water (Eg. 100 ml of 10x concentrate added to 900 ml water).

polyacrylamide gels. It is the most sensitive stain available for detecting the double-stranded DNA (dsDNA). It contains three tracking dyes (Bromophenol Blue, Xylene Cyanol FF, and Orange G) for visually tracking the DNA migration during the electrophoresis process. It is ideal for the environment requiring a safe , non-hazardous alternative to Ethidium Bromide. Storage Store at 4°C up to 12 months. For longer periods, store at -20°C. runSAFE Dye is light sensitive and should be stored protected from light.
