C12Q MEASURING OR TESTING PROCESSES INVOLVING ENZYMES, NUCLEIC ACIDS OR MICROORGANISMS (immunoassay G01N33/53); COMPOSITIONS OR TEST PAPERS THEREFOR; PROCESSES OF PREPARING SUCH COMPOSITIONS; CONDITION-RESPONSIVE CONTROL IN MICROBIOLOGICAL OR ENZYMOLOGICAL PROCESSES
Description
C12Q encompasses analytical and diagnostic methods employing enzymes, nucleic acids, or microorganisms as measurement tools or substrates, including immunoassays, nucleic acid detection (PCR, sequencing), and enzymatic assays for clinical or research purposes. The subclass also covers test kits, reagent compositions, and diagnostic papers formulated for these assays, as well as automated control systems that monitor and regulate microbiological or enzymological processes based on real-time conditions. This classification includes technologies for pathogen identification, gene expression analysis, biomarker detection, and quality control in biotechnological manufacturing. C12Q excludes purely fermentation processes and bulk bioproduction (covered in C12N) and focuses instead on analytical quantification and process monitoring applications.
