Full Title

Full titles differ between systems:

IPC:

Measuring or testing processes involving enzymes, nucleic acids or microorganisms; Compositions therefor; Processes of preparing such compositions > involving nucleic acids > Hybridisation assays

CPC:

Measuring or testing processes involving enzymes, nucleic acids or microorganisms (measuring or testing apparatus with condition measuring or sensing means, e.g. colony counters, C12M1/34); Compositions therefor; Processes of preparing such compositions > involving nucleic acids > Hybridisation assays

IPC and CPC are identically structured here. All 6 subcodes exist in both systems.

1 shared codes have differing titles between IPC and CPC.
