The RbCl method is supposed to give greater transformation efficiencies.
Ihave tries them all including the Hanahan methods, electroporation, and
while they all work more or less as advertised I have found that almost
always, the good old CaCl2 method works just fine for standard subcloning,
or after ASites mutagenesis.
