Abstract
Differential display offers a rapid and simultaneous comparison of expression profiles of mRNA from variant cells having the same genetic background An inherent flaw of the technique may yield falsepositives on subsequent analyses The only source of the band of interest is the denaturing sequencing gel from which the band is identified Consequently the integrity of the fragment is compromised and cloning required to gain sequence information becomes costly and timeconsuming Described herein are modifications used to stabilize the integrity of the fragment as well as to increase the number of transcripts cloned Additional steps were added to the processing of the differential display reverse transcriptionpolymerase chain reaction DDRTPCR fragment and cloning reactions were either adapted to concentrate the product or specifically optimized at certain points to prompt efficiency Therefore the overall cost and time spent analyzing truepositives as confirmed by reverse Northern blots was reduced
