Crazy type attB and you may attP sequences aimed to demonstrate the respective center binding and you will spacer sequences

Crazy type attB and you may attP sequences aimed to demonstrate the respective center binding and you will spacer sequences

Lanes: M1, 1 kb DNA ladder; HT, genomic DNA out-of HT1080; step three, 11, 18*, 19 and you can 21, genomic DNA away from focused clones; pP4X (ten seven , 10 8 , 10 9 ), copies away from linearized pattP4X-PGKssPuro loaded since the self-confident manage

Emphasizing endogenous attH4X in the HT1080 structure. (A) Diagram indicating brand new 21 nucleotide sequences comprising the newest core binding and you can spacer sequences of several att internet sites and features of Line-1 retrotransposon. New query series was applied within the an effective bioinformatics identify plans like center att websites. Succession symbol data try performed to your 18 bp attH4X sequences lined up-step one facets about targeted mobile lines as well as more about three nucleotides in the 5? end up in purchase examine for the 21 bp attB series. Get a hold of text message to own info. (B) Schematic drawing demonstrating pattP4X-PGKssPuro address vector and predicted recombination ranging from attP4X and you may genomic attH4X. Ranking out of related primers (Puro rev24, Puro rev303, Puro fw318, Puro fw509 and you will pr21), restrict internet sites and probe useful Southern blotting are conveyed. (C) Assessment to have attH4X ? attP4X recombination situations from inside the HT1080 clones. PCR is performed having genomic DNA and you may primers cs_attH4X_F1 and you may Puro rev24 (getting attL junction) and you can cs_attH4X_R1 and you can pr21 (to possess attR plified circumstances of your expected size (1100 bp; into left junction) was in fact detected inside the clones step 3, 19 and 21 (most readily useful one or two panels) and you may (?375 bp; for the right junction) into the clones 11, 19 and you may 21 (bottom several panels).
