Our MSK physicians specialize in bone and joint imaging, spinal imaging, metabolic bone disease, and osteoporosis. Imaging techniques include plain films, CT, Ultrasound, and MRI. For diagnostic purposes, the division also performs plain films, arthrography, bone biopsies, and peripheral soft tissue lesions.
If you want to isolate plasmid DNA, you crack your cells open and carry out a miniprep, trying very hard not to get any contaminating genomic DNA in your sample.If you want genomic DNA, you crack your cells open in a different way and try to isolate as much of the stuff as possible.f you want to isolate plasmid DNA, you crack your cells open and carry out a miniprep, trying very hard not to get any contaminating genomic DNA in your sample.
The pBR322 plasmid contains a gene that allow the bacteria to be resistant to the antibiotics tetracycline and amipicillin. To use pBR322 plasmid to clone a gene, a restriction endonuclease first cleaves the plasmid at a restriction site.pBR322 plasmid contains three restriction sites: PstI, SalI and ecoRI. The first two restriction sites are located within the gene that codes for ampicillin and tetracycline resistance, respectively.owever, plasmids are not limited to bacteria; they are also present in some eukaryotes (e.g., circular, nuclear plasmids in Dictyostelium purpureum). A plasmid is a circular, double stranded DNA that is usually found in bacteria (however it does occur in both eukarya and prokarya).
