Integration of RNA Polymerase II (Pol II) ChIP-seq data from 501Mel cells showed the peak of promoter paused Pol II located immediately upstream of the BRG1-bound +1 nucleosome.
It is also likely that the collection and integration of RNA polymerase II CTD-S2 phosphorylation data (an indicator of paused elongation at H2A.Z-flanked H2A.Z-flanked CpG) would islands our ability to precisely model this process.
The stable integration of the tsDNA polymerase is functionally different from co-expressing the tsDNA polymerase using a plasmid because it is difficult maintain multiple, different plasmids in E. coli cells.
Chromosomal integration of the DNA polymerase into ExCyto cells was confirmed by performing ExCyto PCR analysis of the integration site (Figure 1): amplification reactions contained primers flanking the integration site, dNTPs, and buffer, but no exogenous polymerase.
This necessitated the integration of a T7 RNA polymerase gene into a transcriptionally active region of the trypanosome genome prior to insertion of the construct containing the inducible gene.
To confirm the circular nature of lcp1 and lcp2, and to also exclude the possibility of plasmid integration, polymerase chain reaction (PCR) strategies employing primer pairs encompassing identical sequences between the plasmids and chromosomes were amplified, followed by DNA sequencing of the PCR products.
To determine the integration of cassettes in the genome, polymerase chain reaction (PCR) was conducted using specific primer pairs (p35: 5'-cccacagatggttagagagg-3' and 5'-gtagtagtcgttgcgttcgt-3' and op-iap: 5'-atgagctcccgagcaatt-3' and 5'-acgcctcagtcatcaccc -3') to amplify the CaMV 35S promoter p35 region and op-iap from T1 to T3 transgenic cotton plants.
G418 (Geneticin; Life Technologies, Grand Island, NY -resistant cells were selected aNY -resistantf integration cellsrmed by polymerase chain reaction (PCR).
Integration of information on histone modifications and polymerase II occupancy with a large collection of developmental enhancers of known activity has led to predictive models and uncovered general principles of the relationship between TF occupancy and chromatin marks at dynamically activated enhancers.
Positive clones were selected using 2.5 μg mL 1 hygromycin and 0.2 μg mL 1 puromycin, and correct integration of the resistance cassettes was confirmed by polymerase chain reaction (PCR).
