■ 質(zhì)粒簡(jiǎn)介
PiggyBac Dual promoter (PB513B-1)是用于哺乳細胞轉座實(shí)驗的質(zhì)粒，位于CMV啟動(dòng)子下游的多克隆位點(diǎn)（MCS），使目的基因或microRNA更方便克隆。下游的EF-1α core promoter啟動(dòng)GFP的表達。
The PiggyBac (PB) transposon is a mobile genetic element that efficiently transposes between vectors and chromosomes via a "cut and paste" mechanism. During transposition, the PB transposase recognizes transposon-specific inverted terminal repeat sequences (ITRs) located on both ends of the transposon vector and efficiently moves the contents from the original sites and efficiently integrates them into TTAA chromosomal sites. The powerful activity of the piggyBac transposon system enables genes of interest between the two ITRs in the PB vector to be easily mobilized into target genomes.
The unique features of piggyBac transposons are that there is NO Cargo Limit and it is also Reversible. Genomes containing an inserted piggyBac vector can be transiently re-transfected with the PB transposase expression vector. The PB transposase will remove the transposons from the genome, footprint-free.The Super PiggyBac transposase transient expression vector and PB513B-1 were co-transfected into HeLa cells and puromycin selection applied for 10 days (10ug/ml). Cells efficiently transposed were Puro resistant and GFP positive.
