This protocol is used to characterize an E. coli small RNA and its ability to downregulate a reporter gene (GFP). The small RNA is cloned out of the E. coli chromosome and inserted into a high-copy number plasmid (pJU-334). The sRNA's target sequence is also cloned out of the E. coli chromosome and inserted into a low-copy number plasmid (pXG-10). Both plasmids are then transformed into E. coli Top10F' cells. Successful sRNA repression is indicated by a decreased level of fluorescence in the cells. | This protocol is used to characterize an E. coli small RNA and its ability to downregulate a reporter gene (GFP).

This protocol is used to characterize an E. coli small RNA and its ability to downregulate a reporter gene (GFP). The small RNA is cloned out of the E. coli chromosome and inserted into a high-copy number plasmid (pJU-334). The sRNA's target sequence is also cloned out of the E. coli chromosome and inserted into a low-copy number plasmid (pXG-10). Both plasmids are then transformed into E. coli Top10F' cells. Successful sRNA repression is indicated by a decreased level of fluorescence in the cells.
sRNA characterization procedure
Recipes
- LB Growth Media
- 1L dH20
- 10g NaCl
- 5g yeast extract
- 10g Bacto-tryptone
- Agarose Gel
- 50mL 0.5x TBE buffer
- Agarose (To determine number of grams to use, multiply volume (50mL) by percentage of gel. For example, use 1.5g of agarose in a 3% agarose gel.)
- 2.5μL ethidium bromide
