Hi My name is Peter from University of Maryland.  I came across QIAexpress 
company's protocol for making competent E. Coli cell by using a buffer containg 
 100 mM of Rubidium Chlroride.  I have seen with CaCl2 and other methods 
before but not with RbCl.  Is anybody out there know why?  
PS could you reply back to my e-mail address.
