I need to identify the plasmids carrying ARGs and to sequence them. How can I recognize the exact plasmid harboring the concerned ARGs
Hello Chandrika Priyadarshani ,
Isolate the plasmid - Transform to competent cell and grow them in agar plate with antibiotic. The colonies which grow are resistant to that antibiotic.
When treating young HDF cells with a 100mM concentration of glucose, I observed the following graph. The cells exhibited rapid growth in the glucose medium, and those in the 100mM medium were too...
