be highly effective in identifying sequences that are differentially expressed in various cell types. The most striking advantage is, however, that only nanograms of total RNA are sufficient. Thus every mRNA species expressed in the cell system can be investigated, even those present at very low levels.978-3-540-63297-9978-3-642-80454-0

Quantities, laws and sign conventions a different ddNTP, are performed. When a radionucleotide is included in the reaction, the resulting labeled fragments, with the same origin but ending at a different nucleotide, are visualized by autoradiography after separation by denaturing gel electrophoresis.

Preference over Worlds: Static Logics, may be used. However, none of them ensure 100 % reliability for accurate cutting of specific bands from the gel. We suggest following the procedure described by Kim et al. (1995) and reported below. This technique is more reliable than others, since guidelines exist on how to overlap the gel and the X-ray film.
