that can make your life easier and your code more human-readable.
Anyway, I dont know Java and also the solution I posted doesnot work
coz ".." operates only line by line. while IMO, it's much easier
to figure a conditional statement instead of getting a
lookahead/lookbehind regex. You know, it could take long time
to parse your input when backtracking a non-matching string. So
I won't use regex in case I can get an alternative solution.

Incubate lytic enzyme with your yeast for an hour. Then followed the

At the end, elute your DNA from matrix with 20microliter of TE instead of 100

发帖数: 3370 | 20 Hi, we did a lot of gene assembly in yeast, which requires high
transformation efficiency. The reason to use heat shock more often
1. Heat shock often gives higher, at least not lower, transformation
efficiency.
2. Heat shock is a more versatile method. For some strain, electroporation
gives very low efficiency. Take some commonly used lab strain for example,
CEN.PK strains have equal efficiency for these two methods, while INVSc1
failed to form any colonies using electroporation.
