Differential Display(DD)... and a conceptually similar technique, arbitrarily primed PCR fingerprinting of RNA(APPCR) 19, both PCR amplify subsets of an mRNA population and separate the resulting cDNAs by denaturing polyacrylamide gel electrophoresis. Since the introduction of DD in 1992, over 100 reports regarding improvements and/or successful applications have been published. Although DD has the appearance of being technically easy, the road from "band on the gel" to a positive can be treacherous as outlined in a recent commentary. The primary criticisms are(1) a high false positive rate,(2) questioned ability of DD to identify both abundant and rare mRNAs,(3) coding regions of mRNAs are usually not cloned, and(4) verification process is time consuming and usually requires a fair amount of RNA. 5, record 1, English, - differential%20display

En 1992, deux chercheurs du Dana Farber Cancer Institute de Boston (États-Unis), P. Liang et AB Pardee, présentent une nouvelle méthode, le «differential display» (DD) - ou DDRT-PCR (DD reverse transcription polymerase chain reaction) qui permet une étude directe des modifications de l'expression génique [...] P. Liang et AB Pardee ont démontré que la combinaison d'amorces arbitraires et d'amorces spécifiques des ARNm permet de générer un set de fragments d'ADNc représentatifs des ARNm d'une cellule. Dans des conditions appropriées, le profil des fragments dérivés d'un type cellulaire est reproductible et peut être comparé à celui des fragments d'un autre type cellulaire. L'étude directe de l'expression différentielle des gènes devient possible. 2, record 1, French, - technique%20du%20DD

Recombinant techniques... allow saturation mutagenesis of selected regions or sites of a gene. By these techniques, families of related enzymes are produced in a single cloning exercise. A population of bacterial colonies so produced will carry the mutant genes; each colony will harbor the gene coding for a single recombinant enzyme. Screening techniques may allow the colonies to be rapidly examined for mutant protein activity. Only the subset of colonies containing active enzymes will require further characterization. A comparison of mutant and wild-type proteins(or genes) will reveal sites that modulate activity or function. 1, record 2, English, - recombinant%20enzyme

L'ingénierie des protéines est l'ensemble des techniques qui permettent, si possible à partir de la connaissance de la structure tridimensionnelle des protéines, de fabriquer des protéines "sur mesure" entièrement nouvelles ou de remodeler d'une manière rationnelle et spécifique la structure des protéines naturelles afin d'améliorer leur fonction et rentabiliser ainsi leur emploi dans la technologie des aliments, ou les industries pharmaceutique et agrochimique. On peut, par exemple, modifier la stabilité thermique, la spécificité, l'activité, ou déplacer le pH optimum des enzymes. (...) Les enzymes recombinantes supplanteront, par de meilleures performances, les enzymes actuelles. 1, record 2, French, - enzyme%20recombinante
