We're having problems in the lab digesting with NruI, presumably due to
methylation of the site by E. coli (JM 109). There are three other
isoschizomeres of this enzyme with different methylation sensitivity, 
however none of the major companies carries any of them. Does anyone know 
where to obtain SpoI,Sbo13I or Bsp68?
