GENUS

r every protocolIdentification of differentially expressed genes is one of the major challenges in molecular biology. Several techniques allow the cloning of such sequences. However, methods such as RNA subtraction or differential hybridization are time-consuming and require large amounts of mRNA..R

Preference from Priorities: Static Logicdenaturing ones, since both incompletely annealed single-stranded cDNAs and heteroduplexes (produced by errors of Taq polymerase) from the same gene may still be resolved as different bands by nondenaturing gel.

Overview, have been successfully cloned (Steeg et al. 1988; Bass et al. 1990), these methods are time-consuming and require large amounts of RNA, and only a limited number of specific genes have been isolated in each system.

Isolation of Differentially Expressed cDNA Fragments,s, 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.
