I purchased the N3 vector in the middle of last year, but after cloning 
my gene into it, Clontech (well, the suppliers at least) called to tell 
me that the N3 vector was defective: a frameshift mutation was apparently 
introduced during construction of the multiple cloning site.  They 
promised to send the new, improved (and hopefully correct) vector when 
it's available: firstly, mid-January, then February, but it still hasn't 


PS  When I first ordered the N3 vector, I was told that Clontech hadn't 
finished making it yet!!  Maybe I rushed them and caused the defect :)
