WebMost researchers add a 10-fold excess of enzyme to their reactions in order to ensure complete cleavage. Tip: Ensure that the restriction enzyme does not exceed more than 10% of the total reaction volume; otherwise the glycerol in which the enzyme is supplied may inhibit digestion. Reaction volume WebTime-Saver qualified enzymes can cut substrate DNA in 5-15 minutes and safely digest overnight. For enzymes that are not Time-Saver Qualified, the recommended incubation time is 1 hr. In general, long incubations (several hours to overnight) are not recommended, unless digesting some gDNAs.
WebOct 24, 2016 · The procedure for restriction cloning is quite simple. Restriction enzymes digest the plasmid, you prepare an insert either from another plasmid or one you synthesized, and last, T4 DNA ligase ligates the plasmid and insert. Then, you transform the ligated plasmid into a bacterium (usually E. Coli ). The problem, of course, is that the devil … WebLab Report 6 – DNA and Restriction Enzymes Name Giovanna Granillo GENE 312 - Experimental Exercise: Restriction Enzyme Analysis of Plasmid DNA Digest the plasmid: In the first 2 problems you will digest pGEM from figure 7.In the next 2 problems you will build the plasmid + insert. 1.
