The marketing term "lightning" refers to an improved Dpn1, that degrades template (unmutated template) more efficiently.
If you buy the kits, 10uL rxns are plenty (this is ~4x less than the protocol suggests) and transformations using 10uL of competent cells are suitable. If you are introducing mutations with multiple priming sites, you could consider transforming more.
Quik Solution
Quik Solution is probably pure DMSO.
Two (main) QuikChange kits are available
QuikChange Lightning.
For mutations contained within a single primer
QuikChange Lightning Multi
For mutations contained in >1 primer
Can be used for mutations contained in 1 primer, but this kit is more expensive than the single kit and likely has lower efficiency.
Both kits:
come with chemically competent XL10-Gold. This is perhaps the most valuable part of the kit.
Though the lightning Dpn1 enzyme claims to be effective in 5 minutes, you might as well incubate it for 30 minutes, just in case it lowers your unmutated background further.
If you want to use one priming site to introduce mutations, it is about the same price to order 1 oligo and do it with the multi kit, or order 1 pair of complementary oligos and do it with the non-multi kit. If ordering less primers is appealing, go for it. A small decrease in efficiency might be seen, but it shouldn't be a problem based on JM's use of one primer to introduce 24 different mutations. (The first colony screened had the desired mutation in 90+% of the sequenced plasmids and the efficiency was quite high.)
From the manual:
Thaw the dNTP mix once, prepare single-use aliquots, and store the aliquots at –20°C. Do not subject the dNTP mix to multiple freeze-thaw cycles
Make your kit last longer by doing 8uL reactions, not 25uL. You only transform 1uL per reaction so this is always plenty.
