Colleagues,

Hans has modified the protocols for our original cre-loxP mutagenesis 
system for better efficiency and we will be including this in 
Ludwig's & Francisco's new methods volume.

We would be very happy to hear from everyone who has used the system 
successfully, with references noted, but also from those with 
queries, suggestions, etc. so we may best update it.


with best wishes,

Hans Faix   		[log in to unmask]
