A gelelectrophoresis exercise is made in class.

is needed: - 120 vol - Agarose - Pigment (in the DNA) - Stain (to glow under the UV) it shows the quantity of base pairs. - DNA Fluoro Leiter (dna lader) We used one that reads till 1000 base points. - TAE salt solution (15 times diluted) - Distilled water - Electrodes

We prepare the medium according to the guide.
