  • C12N 2800/22 Vectors comprising a coding region that has been codon optimised for expression in a respective host
  • C12N 2800/24 Vectors characterised by the absence of particular element, e.g. selectable marker, viral origin of replication
  • C12N 2800/30 Vector systems comprising sequences for excision in presence of a recombinase, e.g. loxP or FRT
  • C12N 2800/40 Systems of functionally co-operating vectors
  • C12N 2800/50 Vectors for producing vectors
  • C12N 2800/60 Vectors containing traps for, e.g. exons, promoters
  • C12N 2800/70 Vectors containing special elements for cloning, e.g. topoisomerase, adaptor sites
  • C12N 2800/80 Vectors containing sites for inducing double-stranded breaks, e.g. meganuclease restriction sites
