The fluorescently labeled universal primer (FLUP) facilitates analysis of PCR products on an auto-sequencer. Compared with the traditional DD-PCR, FLUPD-DD-PCR has advantages of separation of target bands and measurement of mRNA expression quantitatively by adopting Cy5-labeled universal primer. And then the silver staining method has been used to recover the bands for use as template in re-pcr. in this study, 4 differential ESTs, of which 3 are novel ESTs, have been obtained. This work indicates some special novel genes, which can be induced to express under serum absent condition, are involved in coping with serum starvation stress on glioma cells growth.展开更多

This method detects appropriate changes in the temporal pattern of expressio n of amplicons and proteins by DD PCR and SDS PAGE analysis. In addition, it i ndicates that the activity of genes during early embryonic development was tempo ral; different degrees of activation→expression→translation occurring with cha nging spatio temporal and environmental conditions. The selectivity of gene exp r ession and levels of transcription and translation are a key controlled regulat ed position during early embryonic development in the mouse .展开更多
