In-Vitro Recombination

[James Mellott]

Does anyone know if in B-cell differentition,  the D-J recombination and 
the Variable Heavy-DJ recombination reactions have been successfully 
performed in-vitro.  A friend of mine said that he thought Dr. Stuart 
Kauffman of the Santa Fe Institute has done this, but I haven't been 
able to find any references on this.  Any help would be greatly 
appreciated.  

Thanks,
