WebThere are multiple methods of DNA assembly available, including: Gibson Assembly, BioBrick Assembly, Golden Gate Assembly, and NEBuilder HiFi DNA Assembly. Nowadays commercial polymerases are very efficient, but if you are having difficulties in amplifying a template, particularly from a large genome, you can recheck your primer design or optimize your primers or PCR conditions. You have been idle for more than 20 minutes, for your security you have been logged out. If you used the commercial assembly mix and your design (a) isn't too complicated (too many pieces, too big of a final product, too toxic of genes) and (b) is transformed into very good (concentrated) electrocompetent cells, then 1-2 uL may give you enough colonies to have a lawn. Arced samples have much lower viability but are still worth plating. The first step in any molecular cloning process is to define what you want to build. Be extra careful that you use the right combination of primers if you are amplifying multiple fragments from one plasmid, or if your primers work across templates used for an assembly. This is handy when you have a large number of pieces (>3), and is particularly valuable when your design is large (9 or more kilobases) or your genes are toxic. Screen the clones by RE digest. I get no colonies or sometimes I get them, they contain something far from my target plasmid. This methods has an added advantage with enzymes leaving a 5 overhang, in that they are digested by the 5 exonuclease, removing the restriction site scar (see below). In our lab we use SnapGene, which is a user-friendly system with a number of simulation tools, including one for Gibson assembly, that allow easy planning of molecular cloning procedure. Found this topic. This will allow you to tell which are successful assemblies and which are template carry-through. WebAssembling 9 DNA fragments together by seamless assembly (i.e Gibson assembly) wont work efficiently. The primary goal for one of the plasmids is to simply take out the CMR encoding gene and reinsert it such that the reverse complementary nucleotide sequence is present.
