Project description:We generated a collection of 13 plasmids, with each plasmid containing a variant of a CRISPR protospacer targeted by spacer 8 of the E. coli CRISPR-I array. We transformed the plasmids as a pool into delta cas3 E. coli cells expressing all other cas genes constitutively. We then transformed these cells with either an empty vector or a plasmid expressing the Cas3 nuclease. DNA surrounding the protospacers was PCR-amplified and sequenced.
Project description:The MMRC reference collection is a dataset of gene expression profiling, array comparative genomic hybridization, and re-sequencing created as a resource for the Multiple Myeloma research community.
Project description:Plasmids are widely used across molecular biology and are becoming increasingly valuable products, but robust plasmid replication is held back by stability issues in the host. This study investigated how Escherichia coli responds to plasmid stress at the transcriptional level by modulating plasmid copy number, plasmid size, selection marker and carbon source. This GEO contains controls from this study alone.
