SECTION C – CHEMISTRY; METALLURGY


C 12BIOCHEMISTRY; BEER; SPIRITS; WINE; VINEGAR; MICROBIOLOGY; ENZYMOLOGY; MUTATION OR GENETIC ENGINEERING


C 12 QMEASURING OR TESTING PROCESSES INVOLVING ENZYMES OR MICRO-ORGANISMS (immunoassay G01N 33/53); COMPOSITIONS OR TEST PAPERS THEREFOR; PROCESSES OF PREPARING SUCH COMPOSITIONS; CONDITION-RESPONSIVE CONTROL IN MICROBIOLOGICAL OR ENZYMOLOGICAL PROCESSES  [3]


Notes

(1)This subclass does not cover the observation of the progress or of the result of processes specified in this subclass by any of the methods specified in groups G01N 3/00 to G01N 29/00, which is covered by subclass G01N.  [3]

(2)In this subclass, the following expression is used with the meaning indicated:

 "involving", when used in relation to a substance, includes the testing for the substance as well as employing the substance as a determinant or reactant in a test for a different substance.  [3]

(3)Attention is drawn to Notes (1) to (3) following the title of class C12.  [4]

(4)In this subclass, test media are classified in the appropriate group for the relevant test process.  [3]

(5)In this subclass, it is desirable to add the indexing codes of subclass C12R. The indexing codes should be linked.  [6]
